Not sure if it's been mentioned, but one thing that kind of irks me about Grant's absence is that there was a good handful of original characters created for this show. Keeping that in mind, how hard could it have been to include one of the main characters from the game? I mean, if it was so hard to have a 4th protagonist included in this show, I'm not sure why they didn't just go with Symphony as their timeline. Then they could've had Richter/Alucard/Maria instead of Sypha/Alucard/Trevor. It just seems like a cop out to use Dracula's Curse as the basis for the show without including all of the characters, especially when there's no shortage of stories from the timeline that they could've used. It was one of those things that didn't bother me before the show aired. But after seeing Greta, Lenore, Striga, Varney, Godbrand, the weird sex siblings, etc., made specifically for the show, it definitely seemed like there easily could've been room for Grant if they really wanted to.
