Yup, I rewatched "Manhattan Manhunt" yesterday and while she was being extremely obnoxious because Mac told her -along with Hawkes, but she's so self-centered she doesn't care- to go to the lab, she whined about having seen "a lot worse than that" aka teh dark seekrit! Maybe the writers wanted to develop it more gradually but were forced to speed things up unreasonably due to Anna's personal situation. Anyhow, it was all a mess. I agree with those of you who say Lindsay's incomprehensible features are both the writers' and Anna's fault. She's not Oscar material, but she did quite well in some registers until they forced her to try something different for the sake of oh the drama.
