It was a valid question, the Doctor was trying to be respectfulish, but it seems like he just isn't having it. Floor snacks must not have been worth it. Perhaps Iron Man can build an invention for dialing it back a bit. "I haven't been here long at all, actually. Just passing through, investigating this collective dream." As you do. Completely of your own volition and not at all because of the rift. "Not exactly the criminal table-trap mastermind you're painting a picture of." He considers offering the glowery robot man a hand up, and congratulates himself for the consideration, but opts to leave out the follow-through. "I'm the Doctor, by the way. Not actually a magician."
