Kurt and Blaine share a song and Brittany and Santana finally share an on-screen kiss. (No, they don't.)
Troubletones throw down against New Directions – and Finn takes on Santana.
Santana's smokin', Kurt's hips are rockin', Mercedes is wailin', and Jesse St. Sucks.
Holly Holliday returns, Brittana is on, and they're having the sex talk at the Hummel household.
Brittany still believes in Santa, Blaine finds a way to keep Kurt warm, Becky makes an adorable reindog, and Sue's small heart grows three sizes.
