This is a story about Sara Sidle and her relationship with Grissom throughout the years. It's slightly fictional, as it implies they got together sometime soon after "Butterflied", which is not necessarily what I believe.
The song is called "A Thousand Miles" and it is by Vanessa Carlton. Clips from Omaetoy, PureJorja, and GSR.com.
