Glee - Prom Queen

Well, it is finally Prom time and Quinn is determined to be crowned Queen with Finn as her King, but they are up against some competition this year, including Santana and Dave.  Santana has discovered Dave's true nature and has offered to work with him if he helps her with the Prom.
Rachel's ex, Jesse St. James turns up to help them with Nationals and to go with Rachel to the Prom.  They sing an excellent a cappella version of Adele's Rolling In The Deep.
Kurt asks Blaine to be his Prom partner saying the attacks have stopped now.  Blaine reveals he was attacked after his Prom but agrees to go.  Kurt speaks to Dave who apologises for everything he did but still refuses to come out.
Artie asks Brittany by singing Isn't She Lovely with help from the boys but she still says no!  The Principal asks the Glee class to provide the entertainment at the Prom and they open with a rockin' version of Friday that makes the song bearable!!
The result of the Prom is not what everyone is expecting ##SPOILER ALERT!##.
Dave Karofsky is crowned King but instead of Santana as Queen, the shock reveal is Kurt is voted as Prom Queen!  He is devastated as he realises it was all done to humiliate him.  The bullying hasn't really stopped, it just went subversive.  Blaine convinces him to stand tall and accept his crown but Dave won't dance with him.
The final song is appropriately Dancing Queen!  Glee sing ABBA!  Now THAT would be an episode!
