It's looking more and more likely that Glee is going to be on our screens until the end of time. It just won't stop believin' and it's holding on to that feelin' with an iron-clad grip. Once a high-school school series, it's moving away from the small town to hit the big time in New York. Tonight's episode sees chalk and cheese frenemies Rachel and Santana bump heads when the original bad girl decides to pursue her own Broadway dream. Sue Sylvester appears in all her glory and everyone's favourite vampire from Twilight that isn't Edward, Dr Cullen (Peter Facinelli), returns as the girls' stage director.
