Tony is just taking a break, eating a protein bar and minding his own business, when a pebble pings off the back of his half-open helmet. He turns around, indignant, looking for the culprit. What jackass would—

Oh. That guy.

Instead of saying anything, Tony stoops down to pick a loose bolt up off the ground. He raises his eyebrows, presses the bolt between his gauntlet-clad hands, and then slowly pulls his palms apart to reveal the bolt spinning in a magnetic field. Oooh, aahh! Neat party trick, Iron Man!

Then, without warning, he adjusts the magnetic field, and the bolt is launched out from between his hands, whizzing towards Devin. Catch!
