Santana sort of had it coming to her, but not like this, I really like her character and I felt very sorry for her at the end of the episode. Her bitching is something, but being publicised like this is something else. I could just imagine how she felt when Sue called her into her room, Naya Rivera is such a talented person - both in singing and in acting.
Also, the songs were brilliant. In my opinion, apart from the storyline, the "Hot For Teacher" number was an instant classic. And the Adele mash-up was really good too, they somehow managed to sound even better than Adele.
