I feel like a lot of people in this thread have poor reading comprehension, or they just think the people who've been following the project for over a decade are just talking out of our behinds... I mean how can anyone following this thread be surprised by the fact that season 1 won't finish the Cv3 story, me and plot, and many others have been telling you that since like page 2... Grant will show up, they've just rearranged the story. They want Trevor, Sypha, and Alucard to come together before heading to the castle, which makes much more sense from a storytelling standpoint. Gives us more time to get to know the characters, and for them to interact. I really don't think the first hour and a half of this series just focusing on Trevor walking and whipping would have been very entertaining...
Given the fact that Grant has been captured/transformed into a guard for Dracula we won't be seeing him until the trio starts the march, which seems to be where season 1 will finish. Given that season 2 is 8 episodes, I am guessing it will cover the rest of Cv3's story. It was 3 movies, now it's 12 episodes, each movie adapted into 4 episodes. I expect Grant to appear pretty early in season 2. As he originally was meant to show up in the 2nd movie.
