I'm quite intrigued by some of the returning characters. The child at the castle resembles kid Trevor quite a bit and we also get to see Marie in a few instances but since both of them no longer exist as of now it seems like Gabriel is haunted by their ghosts or his mind messing him up. Or perhaps the toy maker made replicas of his wife and son for him so that he could live atleast a pseudo life with them, which is quite depressing.
The other lady we see, wearing the brotherhood outfit resembles pre- vampire/lord of shadow Carmilla. I wonder what role she has to play. Great to finally see Alucard in his entirety as well, he has got a neat design.
