Yeah the ending of Aria is actually suggested from the start and makes actual sense, unlike the LOS "twist"
The LoS "twist" had a ton of foreshadowing; however, it relied on the user having some knowledge of the Dracula myth:
- Gabriel is a knight member of an holy order, of clear Christian faith; Vlad Tepes was a Christian ruler whose historical exploits are directly tied to the idea of defending Christianity from the Turks.
- Gabriel loses his wife to "the forces of evil" (or at least thinks so) until he finds out he is actually responsible for Marie's death, and this probably leads him to rethink his faith; one of the core myths surrounding Vlad Tepes is that his wife Elizabetha died while he was away fighting the Turks; he later discovered she suicided because she felt continously abandoned by him, and thus he cursed God for forcing him to fight instead of staying with her. Another myth has her suiciding because she's told he was captured and killed. The idea of Vlad falling from "holyness" (as much of a monster he was, he was still seen as a champion of Christianity in Europe) because he blames himself for losing his wife is the core of his mythos.
- One historical fact about Vlad Tepes (at least, it's historically recorded) is that he killed a lover for "lying" to him about being pregnant (she thought she was, it later came out she didn't). He went to her, she hug her and then stabbed her. Much like Gabriel's nightmares., and Claudia's death.
- Vlad Tepes was forced to pretty horrible solutions to push back the Turks (the infamous forest of the impaled) because the King of Hungary, Corvinus, a fellow Christian, posed as an ally but in truth cut his support from Rome. Corvinus is often brought in in vampire fiction as being a vampire or undead of sort too, and often as being responsible for Vlad's transformation.
No need to mention Zobek.
- Vlad is often depicted in fiction as being part of an holy order called "The Order of the Dragon" (Dracul means Dragon, in fact); one trait of the order was the blood red armor and crest.
I (and I guess a lot of other people) was completely expecting Gabe to become Dracula before playing the game. The amount of foreshadowing was overwhelming.
