Keith will be mostly skulking off to the side during the festival, which will probably look Kind of Creepy and may give you an opening for Rhys? Otherwise, he is decidedly trying to enjoy nature at first because that's how he does things (he's using being "a bruiser" as an excuse to not talk to people). OTHERWISE he can see Keith continually heading off to the flowerlands and wonder wtf he's doing (since he's literally doing nothing useful).
