It's All About the Music

What do "So You Think You Can Dance" and "The Vampire Diaries" have in common? "Gravity" Sara Bareilles.
SYTYCD stand out addiction dance this summer was set to this song and The Vampire Diaries second episode also used it. Linking these two shows puts the whole ending of the V.D. episode into a different perspective. My guess is that episode was shot before SYTYCD, but it is an interesting comparison. Is there an addiction to the love of Katherine, long since gone, that has Stephen stalking Elena attempting to win her affections? Is Elena also trying to fill a lost void with a love/attention addiction? Can either of them win if they are both addicted?
