Kizzles has henchmen on retainer whose sole purpose is to find and punch anyone who calls her "Kizzles" so we'll do what we can to avoid that unfortunate situation. Actually, though, the Prides won the League Cup last season so she's probably willing to make allowances to anyone who can get her Prides gear since it's obviously going to be in-demand this school year. And while she's not especially prone to it, she might occasionally fall into the typical teenage girl insecurities but it's not the sort of thing she'd go to her Sporty friends for. That's probably the point of the Popular ones, who she tends to like for just that reason. So FRIENDS, yay!
NO LAUGHTER! Cam is Very Serious and will take everything she says Very Seriously because he's nervous about Quidditch and doesn't want to screw up and humiliate himself, which is a constant worry and something he has trouble bouncing back from. So it could be fun to watch him freak over things that are clearly jokes and take advantage of that a little.
Mortal cupcake enemies does sound hilarious, and "serious" isn't really the point of Acid Pop so it might not hurt to keep an eye out for an opening for that. One bake sale and the Valentine's Day Tea isn't really "endless" even though it probably seems that way when they're preparing for them, so Maura will probably be fine most of the year. Professor Catchlove made a name for herself charming cheese, so it makes sense to me they'd branch out into stuff like that when they don't have other commitments.
