Good thing, too, because if he incapacitated Happy in any way, Tony could not be held accountable for his actions. That likely meant a lot of refusing to leave the lab until he had a reliable driver, but right then Tony was sure he could dislocate a super-joint if pushed, or at least that was what his expression warned as Happy dutifully came out to greet them and open the car doors, inasmuch as Tony could warn while dancing on the frozen sidewalk.
Sure enough, those boots he expected were waiting to be tugged on while they drove and Tony chattered idly at Happy. By the time they reached the Campus and the abandoned medical development lab, he could have passed for a hungry college student at the height of the grungy nineties, from the back, maybe, but Tony didn't seem overly concerned with his sartorial hodgepodge. There was science to do, super soldiers to study, a really cold examination table to invite Steve onto. "JARV, run diagnostics B-E-I, get me on screen with an overlay on the last routine and get a scan of the good Captain to compare. Where do you need me?" he launched as soon as they were in the lab, pushing all that clutter that didn't matter to him off of the desk and tables he commandeered and searching the space for the tools he might need. The hologram that lit up, lifesize alongside the table Tony gestured Steve toward, caught his eye as he took inventory, making him screw up his face and correct, "No--" before JARVIS had a chance to respond to his last request. He washed a hand through it, demanding, "Ditch that, don't need that..." while JARVIS purred, "It's good to see you back so soon, sir. Greetings, Captain Rogers. I hope I can be of some assistance."
