Oh yeah! They have different names (One's name is Vincent and the other is Rose) and have completely different apperances! For example one of them has a bunch of scars all over their face and blue eyes. While the other one has really long hair and hetrochromatic eyes! (they also have elf ears)

If somebody knows them as just the Ravens I'm sure they'd have no way to figure out which one they're talking to and just talk to them like some sort of collective
