Has Tara finally accepted them enough to embrace them as a part of her? Or perhaps there are less secrets that need revealed now, so they can act in a manner not so obtuse? I'm not so sure this will be a permanent change, as Buck does take over Tara's body at the beginning of the episode to look for Tara's missing brother. Perhaps a balance can be found?
Charmaine (Rosemarie DeWitt) is left at the altar last season, and is now determined to be an independent woman. As long as that independence allows her to rely almost entirely on Neil (Patton Oswalt), who buys her groceries, pays her bills, and paints her toenails. Oh, did I mention that Charmaine is pregnant with Neil's baby, and he is not the one who left her during the wedding? Neil wants to make things more official, and proposes, but Charmaine turns him down. Neil continues caring for her, even as she fails to appreciate him. However, Neil does eventually get more forceful after not being there during Charmaine's false labor, and insists on moving in. She relents to that, at least.
These two have been in a delicate dance for years, and it's nice to see some forward momentum. Charmaine is damaged, like her sister Tara, but has different ways of coping. One way is clearly to push Neil away verbally, even while depending on him heavily. Neil is much more patient than most men would be, and the two share genuine affection. At first, I assumed Charmaine didn't want Neil because she is shallow. Now, I think the situation is much more complicated than that. I hope that Charmaine will eventually marry Neil, but what it will take to get her to that point is unknown at this time.
Tara's daughter, Kate (Brie Larson), is learning a valuable lesson many young people are probably repeating all over the country. She seeks employment, but is haunted by her past, namely, sitting on a cake in a sexual manner, something readily searchable on the internet. There is some debate as to how a whole generation of internet exhibitionists will be affected in the long-term by their lack of discerning judgment. I personally feel like so many people post their whole lives that it will matter less and less as time goes on. The writers have chosen the more immediate option, though, and Kate will have a very hard time getting a job in any industry but one where morals are loose.
