(Quentin picked up on a lot of things, although the only coherent ones were involving desire, and that's what he gravitated to. Nothing quite like feeling someone want you as much as you want them. No matter what Penny says, Q knows he desired him sexually. It's deeply appealing and he wants to feel it again. He's needy for positive feelings about him, even if temporary.)

Yeah in general I avoid it, but it was hot here.

(He didn't realize how much he missed it. He misses Eliot in every feasible way, but the physicality of their connection was a gap he forgot about. Quentin knows it may not be fair to use someone to fill that, but on the other hand, this is Penny. He's confident his friend wouldn't see it that way. They can be straight (figuratively) about it.)

We could do it again. (He waves a hand to try and stop what he assumes it an immediate no.) Hear me out. Shit here sucks. Having something that feels good sometimes wouldn't suck. We don't have to overthink it. (He's going for nonchalant but there's anxiety now at the pit of his stomach. He's nervous.)
