But now it's aired, and I don't remember seeing anything like that in the episode!

It's just after John decides that he's going to be the one to experience the, uh, nightlife of Rodney McKay :D When he leaves after telling Teyla, "Yeah, well it's my bad idea," the cut is to a shot looking down on the two of them on their beds (and you can kind of see Carter and Ronon's reflections in the glass).
