LOL Y, I'M SO CONFUSED. THEY WERE FILMING A SONG LAST NIGHT IN THE CHOIR ROOM, RIGHT, BUT IT WAS SET IN 2015? I CAN ONLY IMAGINE THAT HUGE GROUP NUMBER BEING THE LAST THING IN THE EPISODE. AND I'D HOPE THE FLASH FORWARDS ARE SUPPOSED TO BE 'REAL' AND NOT JUST LIKE DREAM SEQUENCES, SO THE EPISODE ENDS IN 2020.
