The engine might have been the nagging distraction in Wanda's safe space, but Iron Man was still turned when she approached him to watch the last of the smoke rising from the glass next to it spiral toward the ceiling and disperse, unseen. That was interesting. Of course, Tony was sure he had just aged about ten years while no time at all had passed, losing an extra five months to his natural lifespan when he finally noticed Wanda reaching out for him. He felt his heart jump and his hair stand up on end, his head dropping to watch her but only stepped away when her touch lingered too uncomfortably long.
"Happy's on his way," he lied, but the phone was ringing and technically the statement would be true shortly, only it rang more than twice and that felt excruciatingly long now in this little apartment. At least in the desert he had a lot of open space; this felt a lot like being back in her bubble and Tony couldn't go through that again. He lifted the Gem up to his chest, hand carefully cupped to admire it sitting benignly in his palm, and continued barely a breath later, "I can get a cab." That wouldn't be so hard, it was New York, he could go now instead of waiting for Hap to come all the way from wherever and eventually one wouldn't mind that he was in the Iron Man. That had to happen all the time. That left the puzzle of the wormhole itself, which Iron Man turned toward again then looked away as though he thought to rearrange the furniture under the hold of a restless anxiety. It was probably best it didn't stay here any longer; if that was what it put them through, if it really was leading them to Infinity Gems, and if Wanda would inevitably prove her inability to rationalize her own limitations. Not even a New York cab would want to strap that to the roof, though. "Are you?" Iron Man returned belatedly, finally looking Wanda's way again, the fragmented question leaving even himself unsure whether he meant 'are you all right?' or 'are you all right to leave with this?'.
