Will doesn't know how he can go back in that room and look at her. She just compared him to freaking Druitt, when all he'd done was try to spare her the knowledge that her life was fictional and everything she'd done up to coming here didn't actually matter because it was all made up. Yeah, that really puts him on the same level as a serial killer. He's pissed enough that he kicks one of the porch's support posts, and that's really unsatisfying because it just makes his foot hurt. So he just sits down on the front step and tries to figure out what the hell he's going to say to that.
