That was unexpectedly sweet. And she had been keeping tabs on him, too. Tony didn't trust it; maybe he had more cause to be worried than he had thought on the way over here. When it turned out she never really intended to show up on his roof and announce her departure via the timestream, Tony went through a cycle of feeling safely beyond such a threat and very dangerously on the precipice of it until he took the initiative himself. It wasn't like he could tell Cap how unnervingly close he was to a sick reality. There wasn't, at least, or so Tony told himself, any more messes Wanda could possibly be making for herself now that she knew enough to put herself on what appeared to be a very cozy lockdown; threat of prison seemed to be good for her behaviour.
Tony's smile didn't falter, but he narrowed his eyes suspiciously as though he could see what her honey sweet facade could be hiding and bit his lip when she lingered a bit too long with his tie, exhaling only when she stepped aside. "And you?" he asked as he slinked away, further into the room where he could get a full view of the engine causing him so much lower back tension, not about to dedicate any more than two words and make it sound like he cared too much about what exactly Wanda was doing, how she was taking care of herself and if she had eaten anything free of MSG. It was just a conversational inquiry into her noodle intake.
