When Alicia falls asleep in Deanna's hospital room

How do you interpret the sequence when Alicia falls asleep in Deanna's hospital room, and then Deanna carefully starts to unbutton Alicia's glove, and when she notices the scar in her wrist left by the suicide attempt she gives a expression of shock and sadness in her face, but despite Alicia wakes up and notices what Deanna is doing, she doesn't do nor does she says anything, pretending to be still asleep.

How do you interpret her quiet reaction to that?? I can understand Deanna's reaction since she was clearly more sensitive and I think she sensed that something painful had happened to Alicia as well since Alicia had tried to kill herself, but Alicia's reaction is more puzzling to me since she always had a harsh and emotionally detached attitude until that point in the movie. Was she becoming more humane and less cold and less angry, and was opening up herself a little bit more to Deanna?? If she had stoped Alicia and lash out at her it would have been more in tone with her overall attitude, considering that Deanna was discovering something that she prefered to hide and was not keen to talk about. But her quiet and calm reaction seems to show that she was becoming more humane and open with her new friend. What do you think??
