i remember 2 weeks ago before the lame baseball game, that when the mash-up episode was over, the preview for the next episode showed rachel with curly hair, and the song 'you're the one that i want' playing in the background. i assumed that the next episode was supposed to be doing something w/ rachel doing a number from grease, but then the next week came and it was baseball. then the next week was baseball again.
im wondering what happened to that episode, cuz obviously, it didnt happen in wheels. also, i remember that episode preview showed puck admitting to the glee glub that he was the father, not finn. what happened? did that episode not happen yet, was it the wrong episode preview?
