That’s “One Man’s Trash,” I think. I added that “I think” because being any more definitive than that would violate the spirit of the episode. You can’t “prove” what did or did not happen in “One Man’s Trash,” or say for certain how much of it occupies a place within the show’s established timeline of “real” characters and events. It does feel like an ellipse of some kind — or maybe a cul-de-sac from which Hannah emotionally escapes when the “relationship” goes to hell in a handbasket. (I love that mini-arc, by the way; it reminded me a little bit of that brilliant answering-machine sequence in Jon Favreau’s Swingers.) What’s happening in “One Man’s Trash” is “real” in the sense that it reflects Hannah’s personality, wants, needs, desires, and fears, and perhaps exposes an unpleasant part of herself that she’d otherwise deny. One “tell” that jumped out at me was Joshua’s vague account of the breakup of his marriage, which included what sounded like placeholder dialogue that Hannah would presumably fill in with real dialogue during revision (“ … real stuff that causes problems, and, uh, marriages to end”). Another is the scene where she makes him ask her to stay over and over and over, in different intonations, like an actor in a TV show produced by and starring Hannah Horvath. “I want you to stay” is one reading. “I don’t want to ever be without you” is another. They’re all so needy, and so fantastical, that they become a kind of verbal pornography, designed to give a secret princess an emotional orgasm.
