Buckle up - there's a lot to unpack here! Gwyneth Paltrow returns for a little sex education and sings one of the most iconic songs ever, "Landslide." Oh, did we mention Stevie Nicks herself was in the room where it happened?! It's also the start of something big … the Brittany and Santana storyline gets off the ground! Plus, Kevin strikes a pose for the cover of Teen Vogue, but we're lucky he remembers because he was hungover for the shoot thanks to Naya's Birthday Party in Vegas the night before!!
