Why this must be read: Mark is Iron Man, Eduardo is Spiderman. Not really an AU, because everything happens after the movie. It's a fusion! It has meta! There is Christy! It rocks! (note: AG, who played Saverin, is the new Spiderman. And RDJ quoted the TSN tagline in the Avengers *fandoms collision*)

"Seriously, could you be any more ridiculous?" Eduardo has come in through the hole in Mark's roof again. Which is infuriating, because it had been a very convenient hole and not at all a problem security-wise, according to JARVIS's calculations. Calculations that had been made before Spiderman started appearing in Palo Alto. "'I am Iron Man'?" says Eduardo. "What the hell was that?"
"That was the truth," Mark replies. "I saw no reason to lie, so I told the truth."
