You know, I still think maybe Luke isn't interested in Justin. I mean, what does this prove, really?
For the record, all of this comic is Luke's fantasy except for the last panel. I fully admit that showing this fantasy is a bit indulgent and could have been skipped given that Luke already made clear his interest in Justin in the previous comic (OR DID HE?!), but hey, how often has the comic in general had something like this between two male characters? I'm not actually sure, but I know less often than with other combinations, so there.
