Alina is afraid and intimidated. The Darkling just killed someone right in front of her, and at this point, that weighs more heavily on her than the fact that he also saved her. So it reads as somewhat uncomfortable when, rather than give her space, he
invades her space and touches her with his bare hand to calm her down. Falling asleep and getting to escape is a welcome change for Alina, though, so she doesn’t necessarily read this as a violation.
