"The rims make everything faster," Xander replied, shrugging. He didn't bring up the part of the rooftop tagging simply because he wanted to twist it into something that Babs could sort of laugh at. A woman flying across rooftops in a wheelchair tricked out with rims didn't seem all that possible, even if the idea seemed kinda cool. "Of course, we could always install some jets on the back of your wheelchair. It could be like a spaceship - on wheels." He chuckled a little at that, the imagery alone proving to be pretty amusing in itself. He was surprised that Batman hadn't come along and made something like that possible. The Bat had the Batmobile all rigged out - why couldn't he manage the same for a friend stuck in a wheelchair? It could have come in handy for when there were villains around or something crazy like that. Villains, hurriedly getting from one place to the other, drag racing....yes. Drag racing. That seemed entirely useful.
"You? Teach me how to cook?" Xander waggled a finger at her. "You do realize how dangerous that is, don't you? Your entire apartment would be at risk of burning down. And if we actually manage to survive that, we'll need to make sure that we've got the American Association of Poison Control number in case I manage to almost kill us with the badness of my cooking." Xander shot her a pointed sort of look. "You do not want to suffer the wrath of my cooking, Babs. It will not end well. In fact..." Xander reached for a his cup, eying it's contents before he shot her an amused sort of look. "That was how we tortured our enemies back in Sunnydale. Buffy'd make me cook for 'em and they'd spill everything once they saw what their meal looked like. I'm serious. Ask Buffy."
Joking around was the easiest way to handle things. It was what Xander did best and it was usually his default mode for when he didn't want to talk about the stuff that was bothering him. As it seemed now, joking around about killer spaghetti definitely was the easy way out for him.
