With a Team of Heroes

Tony's project of collecting Avengers (the only original set!) is disrupted when Pepper breaks up with him. However, despite their less than cheerful host, the rest of the team ends up gathering in the new Avengers Tower, slowly turning into an actual team. When Tony's post-breakup behavior turns out to have long-term consequences, the rest of the team are there to help, and somehow, the world survives the transition to Tony's Avengers without anything exploding.

Or, the one where Steve talks to gravestones, Phil offers to trade a mint-condition card, Clint sits on top of the bookshelf, Tony comes out as bi on live TV much to his own surprise, Natasha doesn't get to murder anyone, and there is disappointment abound because Rhodey has clothes on. And Pepper has a headache because of the Avengers, but then that is nothing new.
