It was almost like they took the entire season's worth of character development for the two of them and threw it together into a single episode. It was just weird to have an episode with nobody else in it.
It was interesting to see her drop everything else when it was her kid, and to see him be willing to help her with it. But it was too much of an infodump episode. "This is why she's screwed up" and "He has a kid" (I'm assuming) and so on.
