He's been focused enough on Beth, bringing her back here, kissing her in the elevator, that he hadn't even stopped to think about Sally so obviously being here and how that might seem. For a moment, walking inside, Chuck is poised to explain before Beth even says anything — which is stupid, really, when they've discussed what this is and it isn't like he'd have had any reason not to be with someone else — but then she moves in close, not seeming to mind, and it's a relief. He doesn't have any expectations here, and if it doesn't work out, then it doesn't work out, but he wouldn't want it to be over something like this.

"Friend of mine got kicked out of her place," he explains, smiling down at Beth, clearly more interested in her than the state of his living room. "I'm letting her stay here a while." It is a good thing, he thinks, that Sally isn't around now, but that's all the more reason not to linger in the living room. Instead, he leans down to kiss Beth again, briefly this time. "I don't think we need to stay out here, do you?"
