people need to understand that Ilya likes when Shane is mean and physical with him. he riles him up seeking whatever it is that makes shane hollander explode. he likes that he has that sort of visible effect on shane.
in the show, we can see this at the stairwell scene, when Shane shoves Ilya against the wall and Ilya like, exhales a super faint 'oh my god' . In the books, it's much more explicitly stated, like there is a paragraph that just says Ilya likes when Shane gets physical with him.
