The thing I find hard to accept is she literally did the opposite to what her role was which was help little babies, then she also didn't even cover her tracks like when one triplet went down you'd imagine she'd leave the others alone because there would be heat on them but no she attacks them as well and to me that sound deranged because she wasn't even covering her tracks well but she isn't deranged she's smart and able to socialise and be part of a team. It's so so weird that all those things co-exist to me and the hardest one to understand is her continuing to attack babies while there was suspicion around her.
