Romilda understood pride, but she also wasn't one to stand by when someone was struggling. Call it a conscience or a hero complex - it had been referred to as both - whatever it was, she had it.
"You'll kick their arse tomorrow," she said with a grin, opening the portrait hole for them with the password. She helped Ginny inside, giving her just enough leverage to make sure she'd make it without (hopefully) making her feel like too much of an invalid. She paused at one of the couches in the Common Room and sat down beside Ginny, though she wasn't in need of a rest herself. Gesturing to the stairs up to her dorm, she added, "Catch your breath, and then we can practice on those. Or I could bring the ice cream down here, I suppose, but we might get interrupted."
The Common Room was generally more busy, certainly busier than Romilda's room at the moment. Romilda didn't really care who saw them together - she did as she pleased - but not everyone appreciated the sanctity of an ice cream party.
She waved a dismissive hand at the mention of her roommate. "Eh, she's a fucking prude," she said. "Not like I can have boys over, with the spells on the stairs up to the dormitory, but she was gagging at the very IDEA of it."
