You've got a lot to read (between Lili and myself), so hopefully we didn't put too much pressure on you (unless you like reading up on them, in which case, good).
If you want the tl;dr:
Solo refuses to leave until Eva leaves with him
Ashling tries to make him leave
He refuses and stands his ground
Ashling offers him a chance to repent for his actions and leave again
He refuses again
She beats him unconscious
Pretty much, but it'd be nice to read anyways. The best course of action for Eva (for further development between him and Solo) would be for her to take Solo's unconscious wolf-body and leave, get an asprin from the nurse or something, and bring him to his dorm. My plan was that when Solo awakens he offers to have Eva stay the night (and sleep in his bed, he in his wolf form can simply lie beside him). But before they sleep, they could just talk (and Solo would reveal something of his past that'd surely bond the two even closer. Best friends level?) and if he's feeling upset still, he could even sing to him (something he'd /never/ do under normal circumstances) if it would cheer him up. I also think Eva might spend the niht in his dorm because his roommate just also beat up Solo.
Thoughts?
