I must admit, when I watched this, I frowned. It was everything I feared it would be. That is, the Blaine Show plus Backup.
FEAR NOT, WARBLERS! Blaine makes sure you guys all have great solos in the other numbers! Because no way are they just doing one song this year. THEY SHALL DO THREE! LIKE ND DOES! AND IN NONE OF THE OTHERS DOES BLAINE GET OUT FRONT SINGING AND DANCING ON HIS OWN! This was just because the coach who is a major perv totally told Blaine to do it for one number at least because he was the captain.
OR, ooooh, maybe Kurt revealed that if ND loses, their Glee Club dies. Not simply loses, but is no longer existent. And Blaine goes "GAAAH! WHY DID YOU HAVE TO TELL US THAT!?" because the Warblers are 75 years old this year and they're not about to be cut from the curriculum any time soon. So they purposely make this a one-man song and Kurt is told to purposely look miserable so it's not exactly throwing the song, is it, it's just making it a little less nice so ND can't help but win...
And I think it's funny that none of us guessed any of those Warbler names. Oh well!
