Tony was not being careful. Tony was having some intuitive conversation with himself with a lot of smiling and touching. Right, well, so much for a little healthy distrust. Wanda stood watching their nearly-silent exchange with her arms crossed, skeptical. So this was what it felt like to be on the other side; there was a time she could have an almost entirely silent exchange like this with Pietro, but she'd never imagined how bizarre it must seem to anyone watching. That it was Tony in a communion with himself was even weirder. At what point, Wanda mused, would this whole weird scenario become masturbatory for them? Pretty quickly, if that pat on Tony's behind was any indication.
Their discourse had, at least, given her a few moments to get over her initial confusion and bring some semblance of calm to her features. That pounding in her head hadn't abated and she had to focus up and concentrate now that her shock had worn off. If anything were immediately wrong with the portal Tony, she suspected (hoped, really) that this world's Tony would have noticed it. Wanda couldn't really sense anything about him other than the fact that he was not the source of the gem throwing a tantrum in her head. Something much worse could have come out of that portal than another Tony Stark.
As the new Tony approached her, Wanda raised her eyebrows but decided there was no reason not act as if his abrupt appearance really wasn't anything more than an intrusion. Two Tonys was not, after all, the weirdest thing she'd ever seen. "It's fine," she waved away his apology and mustered a smile. "We were just having dinner. There are noodles over there if you want them." She nodded towards the bed and the abandoned cardboard box because, with the portal acting up, dinner was probably the last thing on his mind. Tony had his excuse now to give his attention over to the thing he'd really come here to see, Wanda and the Chinese food were incidental.
