"Hey, that's not your fault. That's just time-displaced shenanigans, right?" Tony had no idea how he'd feel if he'd had kids and then they suddenly showed up as adults. That would require having the kids to begin with, but he figured either way it was pretty hard to handle. "But it was good to have a chance to celebrate."
He paused, and added. "I've been meaning to say. Sorry, you know. For my part in all that. Doing my job, but it sucked."
