I do think that Kevin gave her strong hope of hooking up at first then yanked it away so suddenly. It was rather odd even. He went from hot to cold seemingly overnight. But I do also think that Lori develops strong feelings rather easily and I think he sensed that in just a matter of days she probably already had a "relationship" on her mind. She played it off as a crush but I'm pretty sure if Kevin had pursued actual dating, she'd have been ready and willing. I don't mean it as an insult. Letting your feelings get carried away is a natural tendency that many people fight to curb. I actually used to be just like her and that's probably why I can recognize it when I see it. He could have saved his "LOOK, I don't want you" speech for another time knowing the cameras were directly on them. He didn't have to humiliate her, although some may argue that she opened herself up for it. Ugh, romance sure is complicated, isn't it?
