"Glee, Actually" - In a tribute to the film "Love, Actually," seemingly separate storylines come together as one holiday-themed episode, in which Sam (Chord Overstreet) and Brittany (Heather Morris) live their lives to the fullest before the much-heralded Mayan Apocalypse occurs. Meanwhile, Jake (Jacob Artist) and Puck (Mark Salling) spend quality sibling time together for Hanukah, Artie (Kevin McHale) has a holiday dream that changes his outlook on life and Kurt has a Christmas he'll never forget.
