I gotta be honest I didn't like this episode that much, it was basically one of those typical "Detention Themed" episodes where there's always something a group of people want to get. Plus that German Goth girl (Ingrid I think her name was) scared me a bit. Oh yeah and the Marco sub-plot could have been better too imo.
I liked how Janna finally got some focus this season, and Miss Skullnick got to do something too.
Star and Janna play off each unexpectedly well. I was expecting the subplot with Marco to go somewhere further, but I guess it wasn't all that important (still kind of funny though).
