"Yeah. Um, Cho, are you all right?" he asked, though he fully knew what the problem was. But it wasn't Hermione's fault, as Cho seemed to think. After all, he and Cho had barely spoken to each other, up until now. Harry was glad now that he had never made a move on her. Cho was too fake for him anyway. Even if they had dated, she probably only would have feigned interest in him to get information about Cedric, which he hated to talk to anyone about.
"Hermione didn't do anything...," he lied. Let Cho think that he had initiated things, that he had kissed her first or something. He should have initiated them anyway, but he had been too chickenshit.
