Yes! I would imagine that Rose and Scorpius have gotten to know each other a little better since they're roommates! Rose has been living with Regina since shortly after the whole Strigoi plot, after which Regina basically harassed Rose until she gave in and talked to her about everything lol. I think they had already talked/hung out before that. Didn't Scorpius offer to teach her quiddittch waaaay back ages ago?
And Damien is one of two people who explicitly know what happened between Kirk and Rose during the heightened emotion plot, so he and Rose should definitely be getting better acquainted Y/Y? Rose did live at Graeves House for months before the whole Strigoi thing went down, so I'm sure they've talked before, but you know
I am totally down for doing a thread with either of them if you want!
