Arthur showed up. I think he had offered to babysit the kids already for Charlie when they had gone to the ball earlier? Might have to confirm with Emmy, but if that's the case, he would have already gotten familiar with them. He probably wouldn't have brought over a gift unless you count showing off with some advanced magic as a gift. xD He wore something simple. Pants and a plaid shirt. Maybe they don't completely match but his wife taught him enough before she left!
Roxanne showed up as well (with young Fred maybe?) and she played with the kids and chatted with her relatives, because there is always room to be catching up on things when you're from the future. She made it a point to get acquainted with Snow too because I don't think she had a chance to do that before.
