Is it just me or is she getting more mindbroken the further we go through this story?
Early on she could act normal enough infront of others for one,
and she didn't seem to struggle asmuch from just experiencing his presence in a room.
(Not to mention stalking him outdoors.)
Kinda like the more personal their conversations get, (as in actually using names for example)
the more her state of mind devolved.
Also, she's starting to seem more and more likely to actually assault him lately.
