Hi guys long time no see.
I was looking at the guy at the top of the poster and thought hey, he looks like Mathias crossed with the Master Librarian. and is holding the Crimson Stone. But then when I looked closer, I could see his jacket is red, his shirt white, and he has a polka dot neck tie. Which made me go to thinking this might be a redesigned St Germain.
As for the red haired girl with Hector, seeing as she’s shown in Carmilla’s line up, my thoughts are that she’s Laura.
