Just went and rewatched the clip there, it definitely looks like a boy so assuming it’s Carmie, while she should most likely be self isolating etc she does have the right for a support bubble so i’m assuming it’s going to the Carmie and the others in his houseOn her moving in video it looks like Carmie is at the table at 9.25 as her mum is next to her on the kitchen island. He's already hopping between his house and his family home, hope he'll just stay with Kate from now on and not keep jumping around
Edit- spelling
