I want to say it was #36, after Lester leaves the previous chapter, they start fighting about what happened, dan goes to hold her but she doesn't want him to touch her.
I don't think that was her being disgusted by his touch but her telling him that she was majorly pissed at him and not willing to let him just come and hold her and let bygones be bygones, like they usually do. If anything, I believe it was indicative of her not being as welcome to the methods of their relationship anymore as there is another boy in town, as it were.
