While Violet seems to feel even closer to Finch these days, Finch acts like he’s pulling away from her. He seems to be hiding something, he’s unwilling to acknowledge how helpful he’s been to Violet’s recovery, and he also seems to imply that Violet doesn’t necessarily need him. This is most likely a result of Finch’s worsening mental health, but Violet doesn’t know this. And since she knows so little about what Finch is feeling, she can’t help him.
