Rosy is probably my most relevant, as another senior prefect and grump. They can stand around with their arms crossed and glare at people and we can call that bonding.

Then there's Austin! Who's the same house as her and probably spends most of his time around her fucking up things in the garden and acting mildly grumpy but not really for any specific reason. But that's basically the same as being friends when you're in Ebonhide.

Riley will hit on her and make her feel uncomfortable. And Jeffy and Dinah will be LOUD in her vicinity and I'm sorry I'm so sorry.
