Freaking long reading ahead.
Watching some videos from CoD's cutscenes, I though about St Germain and his objectives, and come to realize some things about him that were kinda muddy to me before (I don't know about you guys).
Much has been speculated about Germain, even that he's some sort of omniscient being, but I now think differently: Germain is just a normal dude, trying to save the future where he comes from, from Dracula, and that can travel back in time somehow.
Thing is, Germain does NOT come from the future we know. He comes from one where Hector became the vessel for Dracula, by being possessed by the Curse. Germain's origin era gets rewritten at the end of Curse of Darkness.
First, his initial encounter with Hector:
Here, he mentions knowing everything about Hector, and that he must not pursue Isaac. We all know why: So that Hector don't succumb to the Curse and become the perfect vessel for Dracula. Problem is: at this point in the story, Hector WILL succumb to the Curse, no matter what Germain does. Germain CAN'T stop Hector from becoming Dracula. I'll explain this later.
He also mentions that he's here on behalf of a "greater will" and that "the world hangs in the balance". This greater will, of course, is not some god or abstract concept. It's the continuation of makind itself, and defeat of Dracula, the ultimate darkness, that has actually conquered the future, and has destroyed mankind. Germain is possibly working for an organization in a last desperate atempt to stop Death's scheme in the past.
Here is Hector meeting Death (spoiler alert?) at the Aqueduct:
He goes on to manipulate Hector to follow Isaac, but then he starts feeling uneasy and says he has a "matter he must attend to" and leaves. Of course, there is not any matter. He senses Germain's arrival, and escapes a direct confrontation with him. Germain proceeds to talk Hector into not listening to Zead, but did you notice how he doesn't try as much as the first time? That's because he realized that this timeline is possibly lost, and must really track Death down if he expects to have any chance. This is because Germain can ONLY be an obstacle to Death, and not Hector, and apparently he has already gone through this a million times. Germain is intentionally mysterious because he can't "overstep his bounds". He also mentions that Death is "the one being beyond my recollection". This all I'll explain ahead.
Here, we see Germain and Death bickering. Pay close attention to what they say, what they're bickering about:
Now, some pretty important hints are given to us:
First Death says "Do not go beyond your bounds. You mustn't speak nor act upon matters related to fate. You had better refrain from saying anything... Unsuitabble".
Now... What are Germain's bounds? His bounds are Time. Germain, being a traveller, is "not allowed to speak the truth and not act upon reality", a traveller "merelly passes thru, touching nothing and changing nothing", and this is because it messes with Fate, the domain of another being: Death.
It's quite possible, then, that if Germain says something too overboard, he might end up screwing everything and actually botching his own plan: To keep returning here to annoy Death to... death. More on this later.
Germain concurs with the accusation of messing with Fate, but retorts, asking if it's not ludicrous for Death to be guiding a traveller (Hector) under these circunstances, and Death replies that he's merelly lending assistance to Hector, and that "it's the same with the Curse". What is the same with the Curse? The fact that he's also lending assistance to it, probably by making people's lifes miserable through he guise of Zead.
Germain points out that "this is ridiculous, you have different rules for yourself", and this because Death is a being from Fate, but this SHOULDN'T allow him to cheat and manipulate Fate, in Germain's logic. But as we can see, Death attacks him, and this is because this is a futile discussion: Death shouldn't be allowed to mess with Fate, but he CAN, at least to fix the changes made by pesky time travellers overstepping their bounds. Fate itself demands the Death "fix" things up.
Germain's last words are the golden nugget: "I'll keep returning, until the day you finally surrender".
There is one interesting fact here: Germain's speech seems to imply that Death is NOT bound by a fixed timeline rewritting, but only driven by Fate, able to retain his memories regardless of changes in time. The future both of them already know from previous experience: Hector becomes Dracula in a timeline where Germain doesn't come back, thanks to Death.
They both act as if they had already witnessed this many times before. Remember how he "expected to meet someone else" at the Aqueduct? That's because he already did it before, and failed to hinder Death. This also explains Death being the one beyond his recollection. Death responds only to fate, and not being bound by memory-rewritting changes in time, will act erratically, and thus Germain can't "access" Death like he does with immovable objects in the timeline. Everything will always happen just like before (like Hector, who will always be at the same places), EXCEPT Death, who acts differently, since he's able to remember his past exploits against Germain, and wants to avoid him to get his goals, since he keeps placing himself in front of Death's path.
Germain literally can't recollect Death's actions, because Death is free from the shackles of time predetermination. He will remember how everything happens perfectly, but can't trust his memory when Death is involved.
Germain has no way of winning because he can't mess with reality, and can't access Death preciselly, but he can be a nuisance to him, which happens when he goes back in time: he "resets" Death, who maintains his memories about the past events and his win over Germain, but must do it all over again because Fate requires him to, and Germain won't stop resetting him back to this specific point in time. He expects Death to "finally surrender" by consuming his patience, through having him do it over and over again until he finally gets tired and lets his win go.
It's just like being good at chess, and playing chess with someone bad at it that has the power to go back in time and make you play it over and over again while you retain the memories of your past wins. Eventually you'll simply give up, at which point he'll win and not rewind time, not allowing you to "replay" the match, granting him a permanent win.
Germain has already returned many times, and already is a stone on Death's shoes for far too long, even if he has failed. He's a nuisance to Death.
As we can see, even if Death had won every time, he's tired of having Germain interfering and "resetting" him back to this point. "No one escapes from me" he says, foreshadowing the trap he'll set for Germain on Eneomaos Machine Tower expecting to stop Germain from travelling back in time (and thus resetting Death). If he successfully traps Germain there, he won't be resetted anymore, and this will be his definitive win, but that will end up being his undoing:
Now, the very first line from Germain is a very strong hint: "Oh, an unexpected guest!" Wait, "unexpected" for someone that already knows what will happen with an ummovable object in the timeline (Hector)?
This is because all other times before, there was no trap on the tower. This is a new trick employed by Death, as evidenced by Germain's "I have fallen into his trap at last".
Germain probably teleported everywhere looking for Death, including in the tower, but never once stopped at it long enough to actually meet Hector before. Since Death wasn't there, there simply was no reason to waste time at the tower. But now he's forced to do so, because the trap locks him into place. And he questions Hector "How did you get here?" to which Hector basically replies, "Normally, dude". At this exact point, Death's plan is screwed because Hector's very presence there and his inability to notice any "barriers", makes Germain realize the nature of the trap itself: It makes him into a physical being, unable to travel through time, but able to act upon reality itself, just like Hector! This never happened before, and so he decides to take his chances by fighting Hector, expecting that "all he needs to know will be revealed" to him.
Now, since he was never locked in place before, he never got to actually *waste* Hector's time through a fight. He's physically altering the "keyframes" on this timeline, by making Hector late. He's rewritting fate by simply *actually existing* as a physical being in this time. Hector should be doing specific things at specific points in the timeline, as an immovable object that he is, but now Germain's physical interference was actually able to change Hector's position in the timeline, altering fate's will itself.
After the battle he surrenders, simply because his goal has been achieved: He made Hector late in his pursue of Isaac. It may have been intentional or not, but Germain sure knows that his mere physical presence is enough to change things.
Germain also reveals things about being a traveller, and that he's "only half here". This leads me to think that Germain's REAL body is in his actual home time, while what we see is his conscience/soul/whatever that has been transported to this time using unknown means, and this explains why he can't physically act upon reality. He's literally an hologram of himself. But this trap set by Death made him into a physical being, able to interact directly with Hector.
He proceeds to say that he "feels a new destiny flowing out of you" and this is obvious to him because Hector is LATE. As I said before, Hector should be at specific places doing specific things by now, but he's not, thanks to Germain fighting him. The very next cutscene will show exactly why "being late" is important to changing everything.
Also, we see that the "barrier trap" has been destroyed. Why is that? Because Germain finally succeeded in altering fate! At this exact point, Germain won and Death lost. That's why he "sends Zead his regards". He's gloating his win. Fate itself has no need for Death to win anymore, thus there is no reason for Germain to be trapped. He is simply not travelling back to this time anymore, and the timeline has been successfully rewritten.
"But he could lose Hector's time on purpose just by talking to him like he always does!"
Not exactly. Hector has already demonstrated that if Germain keeps appearing too much, he'll simply stop listening. The fight IS important to slow Hector down.
And as for the next cutscene:
Tell me, what would have happened if Hector had arrived one-Germain-boss-fight earlier?
Simple: He'd arrived soon enough to face Isaac alone, before Trevor OR along with Trevor. In both cases, Trevor would eventually appear, and as we can see, Trevor is more than enough challenge for Isaac.
In this version, taking Trevor's blood is useless because even if Isaac can do it, he can't make his escape. He exploited Hector's late arrival and Trevor's distraction to escape, but in this version he'd need to take Trevor's blood BEFORE escaping, and with Hector being present earlier, this would be probably impossible.
Now, Hector may not be a challenge to Isaac, but as I stated before, Trevor is. In this version, Trevor would make up for Hector's handicap, and actually kick Isaac's ass enough for Hector to deliver the finishing blow.
This is the twist of fate that was thwarted when Germain challenged Hector to a battle. Germain changed fate simply by making Hector arrive at the "wrong" right time.
Hadn't he intervened physically, Hector would have arrived earlier, and made Isaac's escape impossible, allowing for Hector to get his revenge by killing him. Now, what happens if Hector kills Isaac without any Julia to move his heart? This happens:
If Trevor was there on the caves with him, and Isaac couldn't have made his escape, Trevor would have taken up on Hector's handicap and beaten him to a bloody pulp, allowing Hector to deliver the finishing blow. Death would've appeared and taken Hector to be used as Dracula's vessel. Evidence for this is that Death appears on the previous cutscene JUST as Trevor is leaving, and appears rambling about a "lost opportunity", no less. What opportunity? The one to kill Isaac and get Hector to succumb to the curse. But Hector says that he'll still pursue Isaac, so Death thinks everything is fine, and simply postpones his goals by imediatelly telling him where Isaac is. It's all nice and dandy, until Hector tells him about Germain's regards.
Now just look at Death's reaction when he confirms that Hector met Germain while in physical state there. It has "Oh fuck this shouldn't have happened!" written all over it. Indeed, it shouldn't have happened, because now Germain found a legitimate way to mess with Fate, and here is where Death knows that he must abide to Fate's will that now is "Dracula must get ressurrected through an imperfect vessel, and be defeated".
On the cutscene above, Death does mention the Hector needed his powers, but NOT because this was needed to ressurrect Dracula, but because it was needed to properly be able to kill Isaac. With Trevor's help in that "Isaac dies in the caves" scenario, Hector has no need to actually recover his powers.
But here there's also an interesting thing: On this scenario, at the caves, what makes me think that Death would be able to simply take Hector as a vessel?
That's very simple: Hector is still not as powerful here as he is on the end of the game. Remember how hard of a boss Death is at the end of the game? Yeah, now imagine if middle-game Hector had to fight full power Death in this circunstances. 100% sure he'd lose. So this is fate acting again: By making Hector late, Germain managed to open room for Hector to meet Julia who reminds him about the Curse, and to actually make Hector recover his full power, making him strong enough to defeat Death in the future AND Dracula.
Finally, we have the final cutscene:
Germain's speech is not dubious: He legitimatelly doesn't know what will happen now, only that there is the final battle between Dracula and humans. He has already helped Hector avoid his fate of becoming a vessel here, so now he'll go foward, and see if Hector's battle is remembered or if it has started anew, which leads me to believe that something in Hector's story is actually crucial for Dracula's final defeat.
So that's it dudes! I hope you liked the reading. I wrote it because Germain always seemed needlessly mysterious on this story, so I decided to take a deep look into it and find out what Germain is all about;
My conclusion: Germain is a guy that comes from a future ruled by Dracula, where Hector failed and became Dracula's vessel. Death must obey fate (In this case the fate being "Dracula wins") and make it happen, but with Germain's constant interference, Death is actually performing the same task nonstop, until he creates the tower trap, which ends up giving Germain the upper hand.
