Rab has no idea who he is! And probs won't have the patience for him, I'm sorry bb :( Hyper little kids just give him a headache.
Rose actually might have known him, hollaaaaa. Plus she knows Colin, so yeah.
Amelia doesn't really know Dennis, but she knows Colin too so she will be nice and things! If he wants cookies and something let her know xP
Sally-Ann just kind of shrugs. She might have seen him in passing at some point, but that's about it. I mean they were at least in the same house...
Older!Po has no idea either. But people her age, yay! This truly exciting to her, I assure you. Especially after being the only 5 year old... Even if she doesn't know that now xP
