Forms of Love (слэш)

Months after the Avengers' dispute in Germany, the team returns to the US and moves back into the tower. As always, everyone pretends that nothing happened. Tony is just fine with this. He's used to pretending, and he'll be damned if he lets any of them see him flinch.
Tony's the bad guy, after all. He's used to it. He's fine with it. He's good at it.
Only now, there's something far worse loitering around the tower - The Winter Soldier. No one notices the guy at first, but when they do, Tony figures that he should have the soldier's back.
Birds of a feather should flock together, and the bad guys should start a book club.
