"I haven't played soccer since I was back with the brats..." It's said fondly, but likely Xander means Drake's children. That suspicion would be a correct one. "You're on! But yeah, tomorrow."

Or sometime in the future, after he's yeeted back to his bed.

"I don't know how to play gin rummy," he admits, looking over at Siebren and sounding almost...wistful? "But I mean, if you want to teach, I'd like to learn? I don't know a lot of card games. Mostly board games, whatever the Valkonans had at the Lab." Oh, they probably had card games too, but since it was rather likely that involved things like alcohol and more? Xander wasn't invited to those little soirees.

And then he snorts out a laugh. "At least you can be sure you'll get a couple over on me at first! I'm not that quick on the pick-up!"
