Uh oh: Julie's home! She calls out, "Mom?" but gets no answer, so she goes upstairs and opens Susan's door. Surprise! There is Susan, who is naked, and in bed with Karl, who is also naked. Julie sucks in some serious air and lets out a big "oh my god." Susan opens her eyes blearily and says, "Oh! Julie! I thought you were going straight to school?" Julie, flustered: "I needed money for lunch." Karl: "There's a twenty in my pants, if you can find them." Ha! Ha ha! Julie flinches, and then turns abruptly and leaves. Susan and Karl call after her as they struggle mightily to work their way free of the covers.

Downstairs, Julie tips out Susan's purse and grabs money from her wallet. Susan races in, still tying the drawstring of her sweats, and tells Julie that there is a good explanation for the Karl-naked-sex thing. Julie strongly doubts it, but Susan tries to comfort her with the news that Karl and Edie broke up. Julie: "You slept with him the same night he broke up with her?" Susan, somewhat abashed: "Well, I said it was a good explanation, not a great one." Julie gives a disgusted grunt as she grabs her bag and goes to leave. Susan calls after her, but just then, Karl comes in, still buttoning up his pants. Karl: "Hey, Pumpkin!" Julie: "Don't even." Julie leaves, and Susan tells Karl that she feels awful. They agree that they should not have done what they did. Karl: "But I gotta tell you, last night was the best sex ever." Susan: "Wasn't it, though? You were fantastic." Funny! Karl: "I was just trying to keep up with you!" Susan asks why it is that they got so good all of a sudden, and Karl muses that it might have something to do with all the pent-up anger, and their finally figuring out how to channel it. Karl nudges Susan shyly with his shoulder and asks, "So what happens next?" Susan gets up and says she's going to take a shower. Karl: "No, I...I mean with us." Susan: "'Us'? There's no us." But Karl seems reluctant to let go of their newfound chemistry, which he describes as "explosive." Susan: "Karl! Last night was two old friends helping each other through a rough patch. That's it." Karl, plaintively: "Susie-Q!" Susan: "Karl. I want to move on. I don't want to go backwards. I'm sorry." She gives him a big "mwah" kiss on the lips. Susan adds: "But thank you for the explosion. I really needed it." And then she glides off to take her shower. Aw, our little Susan. She's all growed up! Finally.
