Nobody who worked with Walter back when he was Old "I-Am-God" Walter could be anything other than equally messed up, so Evil!Bell made sense to me.

Nothing this show has done to Olivia has surprised me, because I was a huge devotee of Alias and poor Sydney had her entire life ruined multiple times in terrible, horrible ways. She was never possessed by another consciousness or had her boyfriend cheat on her with an alternate version of herself, but things sucked for her in other ways.
