"I will be," she answered, the best answer she could give when she realized that Tony didn't actually care, that he wanted to get as far away from her as possible- the way he'd jerked back from her touch was clear and she could take a hint. What Wanda wanted to do was ask Tony to stay, insist on it, because in the state he was in he definitely shouldn't be getting in a taxi to go lord knew where. What he needed was rest or a hospital, but she knew him well enough to know he'd refuse either option. Fine, whatever, all she wanted to do was sleep for a thousand years and she would whether Tony was laid out on the sofa recuperating or in the back of a cab making his escape from here.
Probably it was best if he did go and took that horrible gem with him. The thought crossed Wanda's mind that Tony ought to take the portal machine, too, but that wasn't exactly feasible at the moment and anyway Nick had entrusted it to her. For all that was worth. Tony was a part of this now, too, like it or not. He'd gone through that ordeal with her and he understood the machine- this monumental task was a burden she would have to share, even if he didn't want to take up the yoke.
There was only last thing to do, then, before she could collapse into blissful oblivion for a few days. She turned away from Tony and tottered to the kitchen, rooting around on a kitchen drawer until she came up with a key that she tossed his way, a key to this loft. "You can come back whenever," she told him and ran a hand over her face, slumping against the counter top.
