I would love love okay- I would love something where the team tries to get Tony to stop drinking coffee. Like, maybe Clint mentions it in passing or something and then they all get in on the discussion and Steve's all 'wow, I didn't know caffeine had side effects like that!' and plays the concerned boyfriend and Tony's going 'guys, no, seriously, guys this is such a bad idea let-me-count-the-ways bad idea, you have no idea what I'm like without coffee but let me just tell you? Not. Good.'

And then they manage to decaffeinate him for, like, a day? And then he crashes or something- hard and becomes completely- I don't know. (I always rather thought Tony would be a high-functioning ADHD person, which would explain why he does all the coffee and explain the inventor thing- well, not that you need to 'explain' inventor, but did you know genius and ADD/ADHD go hand-in-hand a lot? Yeah, right up there with Asperger's.)
