"You wished..." Dean didn't bother with the rest of the sentence. He set down the pizza slice he was working on as well as the beer and pushed them away with a groan. "You just made a wish? Just like that? Didn't think about it at all?"
Yeah, Dean had had some really bad experiences with wishes. He'd had to clean up the mess wishing had made too, and that had not been at all pleasant. He looked at the pizza, the beer, then the girl. Oh, this wasn't going to end well. He got up and started pacing, hoping that he hadn't eaten enough pizza to make himself sick.
"Look. I don't know what it's like back with the Justice League, but I'd think you'd know better than making wishes. Especially in a place that seems to like fucking with people. Or with a Trickster around; that's right, sister, there's a Trickster demi-god if you want to call him that running around." Okay, so Dean was back to calling her "sister." "You don't make wishes. You go for what you want, or you realize there's a reason you can't have what you're wishing for."
He sat back down again with a sigh and looked at her, his eyes soft, concerned, and maybe a hint apologetic for the outburst. "You can't be everywhere at once; believe me, I wish I could be, too. It just doesn't work that way."
