Lance came of course! He ate and drank, carted his tiny dragon BF around when he wasn't cooking things, would take on whatever game challenges and all that fun stuff. Bought Keith one of those digital picture frames last week and has been spending the time since loading it up with whatever photos he could find (assume your characters got hit up for photos for it, thanks). IDK THINGS
Gladio was there with his BFs (and Iris/Talcott maybe?), laid down a few Mario Kart challenges that he probably lost. Ate all the foods, and chatted and chilled, etc.
IDK who else, just yell at me if I missed someone.
