If anything was going to happen, they would have merely mentioned the 'I Love You' in some form
I'm honestly curious, because a few people keep saying this, but why do they need to specifically and directly mention it again? And if they do, why does it have to be right away?

And that kind of sent me on a tangent that doesn't really have to do with your comment, but I'll put it here, anyway XD

A lot of fans seem to think that House and Wilson's relationship just "miraculously" healed, that Tritter was forgotten, and nothing changed...and I don't see that. Last season, House apologized to Wilson twice and thanked him a few times, and nothing big was made of it, or referenced later. Yeah, there was no big, deep discussion about the Tritter stuff (thank god, because that would be lame and OOC), but those actions definitely came as a result of that arc. And Wilson is aware of it - he accepts House's apologies, not because he lacks a backbone, but because he wants to encourage that behavior (if he had walked away, what message would that send to House?) - and his mood improves in the second half of the season up through now. Granted, I think something else is going on, as well, but the writing in this area has been consistent and subtle in my eyes.

...Like I said, tangent.
