Tony is Kidnapped.

I'm pretty sure this was on the kinkmeme, but I can't find it anywhere. Tony is kidnapped and the Avengers don't notice. Tony's been assuring himself that they'll come for him, since they're a team. They don't, and he gets free himself somehow. Then he confronts them in the tower. They didn't even know he was missing, which does not make Tony feel better.

Also, there was an exchange when they first see Tony (who is banged up from his ordeal and limping).
Clint: "Whoa! You should use a safeword next time!"
Tony: "Yeah, because kidnappers <bleep> listen to safewords!"

Anyone?
