Mel maskoftears is taken and unless he came to the Theatre department or to hang out with the Muses probably wouldn't see a lot of interaction. Judas sins_past probably wouldn't interact with him; unless you want to fuck with Judas which would be fine. And Jor talkstosnakes will be watching him really close in the case he goes after Riley...
