If you're not saying that he's saying they actually hook up, then I don't know what you're disagreeing with even. Obviously, the "joke" part of the gay joke you mention is that them having sleepovers/being friendly is considered unusual unless they're in a couple relationship and that's what he's teasing them about. Which is what I said from the beginning. I wasn't saying he wasn't joking with them. I was saying you can interpret his comments as meaning something other than him thinking that the two of them are having sex.
