Once more, Terri is made a bit sympathetic in her marriage to Will. There is a commonly held belief that their entire fight seems one-sided in Will's favor. But keep in mind, Will is having an emotional, if not physical, affair with Emma. When Terri sees them together, it hurts her deeply. To hose who might say that Emma is nicer to Will, Terri has a point when she says to Emma that it's easy to be nice for a few hours a day to someone. No one really knows what goes on in a marriage besides the couple. Terri is surely not all to blame, as she has a well defined personality, which Will would have known before marrying her. She also stays loyal to her husband.
A far worse example of marriage is the one Emma is about to enter into with Ken Tanaka (Patrick Gallagher). Among her demands are continuing to live on separate sides of town and not spending time together after school. Really, who is the worse wife in this scenario, Emma or Terri? If one stops and thinks about it, Terri may actually be a better human being at this point. Emma claims she doesn't want to die alone, but she certainly isn't willing to overcome any of her phobias to achieve the goal, and so it becomes impossible, and cruel to Ken for being an enabler. If one is a fan of Will, how can you wish them together?
While not exactly clear, I assume the episode title "Vitamin D" is a reference to pseudoephedrine being used in Claritin D, which is what it appears the kids are taking, as well as Finn calling them his vitamins.
Hilarious that while Finn is complaining he doesn't have enough time in his life to get everything done, he is sitting and playing video games. I have a suggestion for what he could cut back on.
Quinn is so evil at this point in the show! She is complicit in Terri's scheme to pass off her baby as Terri's. She admits to Rachel, were their positions reversed, she would not be nice to the other girl. She continues to lie to Finn about who the father of her baby is. Is any teenage girl, who isn't criminally psychotic, really this mean? After watching the movie Mean Girls, sadly, I fear the answer is yes. Makes me glad to be a guy.
