Coldplay debuted their song "Fix You" on the final episode of season two. After Summer wins prom queen (alongside *gasp* Luke) and is stood up on stage, Seth makes the grand gesture of running on stage to slow-dance with her. But, once again, the scene is overshadowed by Ryan surprising Marissa, and the song plays softly in the background while they slow-dance in the school carpark. Famously, it is also during this song that Caleb falls into the pool mid-heart attack. It was a big moment for the show.
