Merida and her need something established. Georgia's pretty serious about Quiddy, iirc? For Georgia, at least. Not BOY serious, ofc. SO Merida probably treated her like a rival even before they were captains. But at the same time, Merida's been kind of chill with her in past threading, so maybe it's become a more friendly thing?

I really like her and Melvin's interactions and would love to do more with them!

And then there's Teddy and Porrim and Punzie but I'm blanking for now. The second two are fifth years so I'm sure they AT LEAST know her.
