This scene would actually be in the end credits of Iron Man 2.
Would be exact same scene location as the clip at end credits of Iron Man 1 with Fury.
Late at night Tony Stark walks to his bar in his dimly lit living room and pours himself a wisky.
Stark - "We really need to stop seeing eachother like this"
-Pan shot of living room, Fury standing in shadows by window wall, dark outside pouring rain.
Fury - "You need a better alarm system"
Stark - "I need unexpected guests to use my front door"
Fury - "About that Avengers project"
Stark - "what about it"
-Pan shot to Fury. Lightning thunders outside window. Light strobe effect showing Thor in full regalia holding his hammer.
-shot of Stark's face with eyes wide open
-shot back to Fury with another lightning strike, strobe effect showing Thor again.
Stark - "So much for lightning not striking twice in the same place..."
Last line can be omitted, not sold on it, but the rest would make me ****...
