There's no plausible excuse for Cecilia's power not protect her from such dumb attack. Her power are always active, not to mention that even if they weren't she could've easily activated them since the nesting doll first grabbed her arm. She had time to say "oh hell no" but couldn't protect herself with her ability? Really?
It all went downhill after this already stupid mistake. Unless those things can block your powers, I wonder what excuse will they have - if any - for what has happened.
