House is quite obviously pleased with himself for having gotten that reaction from Chase, all eye rolling exasperation and too little too late protest. It's interesting that he's not backing away now, not leaving now that House has gone so out of his way to insult him and push into his space. Instead, he's leaning in just subtly closer, which is either stupid or brave or both.

"Just the pre-pubescent ones," he dishes right back. Chase's retort is a little too delayed to effectively do what he's hoping, to hide that attraction that House can see relatively plainly.

"Was there a reason you interrupted me?" he asks again, a follow up to that first question of can I help you?
