Loved seeing the parents POV - and man are Santana's adopted parents horrible. I mean, they do the bare minimum as parents (food, shelter, etc) but they're just going to abandon her at 18? HARSH. Good to know that Russell Fabray is just as a big a dick as I thought.

And Glee kids? Infrastructure is both important and interesting (some of us work on those problems yo...)

And Sue, as always, has the perfect ending line.
