Surely it couldn't be considered an invasion of privacy if she put it on the internet. At least, that's what he tells himself while he waits for the next video to load. Even if it were, she's the one that even told him about them. No matter how much he tries, he can't seem to talk himself out of watching them all. Just seeing her guest's name in the title makes him roll his eyes. He tries to remind himself that he has no right, really, to be so protective over her, that she hates him, but that doesn't make him any less frustrated with the way that they flirt. He knows that he was rejected and that he'll just have to get over it, but to watch her laugh and joke with him of all people is enough to make his chest feel tight.
But the flirting is not the worst part. Not even the little jokes made at his expense are the worst, or the way that George spins the story to make him look bad and, even worse, make Lizzie hate him even more. Everything pales in comparison to when he calls her Peach.
