Cut to Sam, standing outside Nathan's apartment door and begging him to speak to her. He refuses to open the door. After she begs and pleads, he tells her through the door that he guesses people can change and that he's very glad she came to speak to him. And as she gratefully accepts this quasi-forgiveness, we can see him (holding his dog) creeping out onto the fire escape and, um, escaping.
Back in the car, Dena tells Sam that she made an effort and that there's really no way to force Nathan to listen to her. Except that Sam had an idea. Cut to Nathan in a parking garage getting into his car. Sam pops up from the back seat and tells Nathan that running away from her was kind of rude. So, New Sam is 0% less stalky than Bad Sam. Nathan screams and wonders how she broke into his car. She seems pretty surprised to discover she had that ability as well. Anyway, Nathan is freaking out and trying to call a neighbor to check on his dog while Sam tries to explain the amnesia to him. He tells her, "Amnesia doesn't exist. It's just a cheap and lazy storytelling device." Oooo, very meta. I mean, Mehta. Zubin Mehta -- he always likes to make jokes about the music he's conducting. Sam explains the amnesia thing, and Nathan actually starts to believe that maybe she's really no longer a crazy stalker woman when a convertible pulls into the parking garage with "We Got the Beat" playing on the radio. Sam's sudden flood of tears undermines the calm, sane façade she's trying to project, and she runs away before Nathan calls the police or hits her with some pepper spray.
Back at home, Regina is sewing a quilt while Howard cleans his gun. Neither one of those things is a euphemism. Samantha has just told them the story, and Regina is just a little upset that Sam liked Nathan enough to stalk him but never introduced him to her parents. She also seems a little unclear on the fact that Todd has dumped Sam. Although I can't really blame her -- they spend more time together than I spend with my boyfriend. (Okay, he's not yet my boyfriend. But he hasn't gotten a restraining order yet, so that still puts me ahead of Sam.) Regina, depressed at the thought that Sam is so lousy at romance that she's never going to give her grandchildren, packs up her sewing and leaves. And then Sam and Howard talk, except that Sam is talking about her problems while Howard is talking about how much fun hunting is going to be, and neither listens to a word the other has to say.
Sam and Andrea are sitting at a table in a bar, talking about how hard it is for Sam to kick the stalking habit. Dena's voice pulls us back to the car, as she complains about Sam and Andrea going out for drinks without her. Sam reminds her that she was at swing dancing class, and cuts back to the bar scene. Sam says that she only stalked Nathan because she felt an overpowering compulsion to make him pay attention to her. Which is precisely the reason that Bad Sam stalked him. Andrea diagnoses Sam as having daddy issues. Which is an official diagnosis in the DSM-IV (or so I've read on the forums). Andrea thinks that Sam didn't get enough of daddy's love as a child, which is why she's so hungry for attention from men now. Oh my God, it's like looking into a mirror. Ahem. Sam thinks that Andrea's crazy, because she has a great relationship with her father. In fact, they just had a fantastic conversation in which he responded to not one thing she said. Sam doesn't want to have daddy issues, but Andrea thinks that being damaged and fucked up is how the two of them get men. Sam decides she's had enough damage, and runs away to find a gun because she's going to go hunting. Commercials.
