You recently started traveling with Trevor and together you saved Sypha. After that, she joined your company

You were looking for the sleeping knight, the Messiah, who lies beneath the catacombs.

When you got there and Dracula's son, Alucard Tepes, turned out to be the messiah. Trevor and Alucard started talking.

Trevor: You're a vampire... I think I'll have to kill you. He said maliciously and chuckled

Alucard: chuckles if you're actually a Belmont... you can.
