waverly - she enjoys the jam jar very much let's be friends!! will talk about anything to anyone really, so once she senses waverly isn't in need of the path's services she probably wouldn't bring it up again unless waverly mentions she is having doubts about her life!
bree & ryder - yes! that sounds good. they are likely to know her by face and name, i'd say! maybe they know by now not to give her a glass cup??
zack - what a cute little bean! please, allow her to talk to you endlessly.
koa - also adorable. though there's an age gap there i can see them perhaps getting into wacky hijinx down the line because it looked fun at the time.
