Help with a Jack & Juliet song?

I know this post is quite lonely, but I hope someone can help me.

I'm planning to do a Jack/Juliet video that shows their history through the season, and how in spite of all the chemistry that existed between them, they don't end up together at the end.

What I ask is that you help me find a good theme for the video, which fit with the story of Jack and Juliet.

I hope someone can help me : D
