Yes, in the DC universe, only heterosexual lovers actually get naked with each other. Actually, I suppose if the ghost of Mort Weisinger had anything to do with it, nobody would get naked in the DC universe. I mean, even Superman wore jammies. Yes, with his uniform under them, of course, just in case.
What's that? Mort Who? Never mind. Old joke. I doubt that anything that happend in 52 would have happened if he were still around.
Anyway, here's Renee Montoya, barely recognizable from her origins in Batman: The Animated Series, cuddling with... with... Darn, did we ever find out who that is? She calls Renee by name several times when she starts shooting at their intruder (Vic Sage, aka The Question), but Renee never does call her name. Ah, well. Life's rough in the Old Supporting Characters' Home. We don't see her again, anyway.
Maybe she's Lucy Lane. That would explain a lot about Lucy's relationship with Jimmy Olsen.
