Eh, it's not impossible to believe. It's possible Wilson is able to distinguish between his medical profession and a sport.
On the topic of the show feeling more like "old times."
I see your point, but....
House's antics have always been a part of the episodes since sometime in the second season, he's pretty much always been up to something, usually something for his own gain over something petty.
Now, I don't quite buy House would tamper with his anklet -knowing the implications- in order to get to got o AC, it would've been more fun to see how House negotiated to go with Foreman, with Foreman having to scheme the tickets out of Wilson. That ending to that story seemed more like House to me, he's always scheming around for his own gain in one way or another, there's also been plenty of times where his personal goals have overcome his focus on the patient.
But, at the same time, he still has some active interest in the case he has always been pretty involved in the personal issues of his fellows.
The ending bit with House talking to Adams (?) about his thoughts on "parents screwing us up" and how Adams' parents screwed her up by not screwing her up.
Then we get our sitcom ending.
I don't watch many (any) fights on TV, but how obvious House and Foreman were in the background was just off and not quite in "realism." But at least the show is more focused on the medical stuff than it has been the last couple of seasons and the personal-issue stuff is most B/G stuff or ties into our POTW stuff better. (Like the stuff this week on wanting to be a part of a child's life and the impacts it can have on the parents and the child -wanting to seek out his birth parents.)
More on the ending: It seemed to "fit" with Foreman's character... sort-of. Foreman has shown to have some degree of respect and like for House, more notably during House's breakdown at the end in season 6's finale when House loses a patient he's connected with. Foreman also went to some professional risk to get House out of prison and back into the hospital and has been working since then to keep House out of trouble. The two have had a good working relationship since Foreman was brought on as not a complete subordinate to House but more as a equal in Season 4 (where House suggests in one episode that Foreman is left in charge when House is away for a reason.)
It sort of worked for me to see the two of them together at the fight, but I think it could've been presented better, perhaps first with Foreman and House walking down the aisle and taking their seats having something of a friendly chat about the ending of House's case, House says '"Hold on a second, I think I've timed this just right..."
Then we see Wilson entering House's apartment, calls out to him, and then his phone rings. Wilson pulls it out, looks at it and finds he was sent a picture, from House, of him and Foreman smiling together into House's phone camera turned in such a way that Wilson can see the two of them were together at the fight. Wilson gets a stunned look on his face, sighs, and sits down to watch the fight on House's TV.
That would've worked better than the rather goofy-ily done ending we got here.
