I kind of disagree about Rebecca being Borderline. I can see why someone might think that, though. I don't see much ideation/devaluation in her relationships, except maybe with Josh but even that doesn't really apply. While Rebecca has issues with abandonment, I don't really see the type that Borderline people have. She's not trying to avoid abandonment (or her perception of abandonment) -- if last episode and this episode was any indication, she already believes she's been abandoned.
