Vic more or less has two sons (praelia and zeroes_and_ones) who can be immature at times, so he'd probably be able to deal with Gavin's most of the time. If his immaturity meant that he was fucking with other residents to the point where Vic would have to step in as Enforcer and tell him to back off, though, that would be another story, but I don't think Vic would necessarily hold it against him.
She would've been up for that! Cherry isn't looking for relationships right now, even though she's not opposed to it at all - she just hasn't found anyone yet, and I don't think she'd look to Gavin for that. He seems like too much trouble ;)
