irl Alice is way more human than 2D Alice. She looks like an actual woman, and her clear eye is much more realistic that the other cartoon's (the inky one could be Alice's "real" eye, only distorted). Maybe Alice had so little personality she kind of got absorbed by Susie. Also, Striker and Fisher from the Butcher's Gang have a realistic eye each. Maybe the ones who got turned into them struggled a lot against the ink and a small part of them was saved?
