They couldn't very well attend a dinner party without a gift, that much was true. Tony had to think about it a moment, having known Cassie had forgotten something all along and wistfully remembering the days oh so long ago when Pepper wouldn't have let him out of the house without straightening his tie (he had forgone it upon realizing his attempts to tie it were clumsy at best, and at least not nearly the perfected art Pepper was capable of). He was still contemplating the loss when he pulled open Wanda's door for her, and gave a kind of distracted nod. "Dessert, sure, there's got to be something open," he agreed. This was New York, after all.
At least someone had hung around to think about all of the basic necessities in his life, and he wasn't even paying this one. He finally gave Wanda that smile when he was seated beside her, turning it off just as easily as it lit up to instruct, "Seatbelt." Right, so, there was a possibility that she was a subversive terrorist, but so far she had been quite dependable and Tony was terrible at picking out gifts. If, somewhere down the road, she showed her hand and tried to shoot him in the head, he could at least look back and appreciate who she had been up until that point.
A few illegal turns and narrowly avoided speeding tickets later, Tony was appreciating Wanda in a 24 hour grocery store. Quite lost, "Why would you advertise 'Open 24 hours' and close the bakery at five o'clock? That's a poor business plan. That's dissatisfied customers," he complained, looking dejectedly on at the darkened counters, probably just full of appropriately kosher cakes. He couldn't even remember the last time he'd been in a grocery store. Did they all practice false advertising? Maybe the fruit wasn't even real.
