Fringe, Season 4

Dunham:
Look, I appreciate what you guys have been doing to prevent closing the bridge, even if it's a long shot. The truth is, I like coming over here. Especially after it rains. [gets a confused look from Olivia] When my world started to break down the conditions in the atmosphere changed. Light doesn't reflect through moisture like it used to. I haven't seen a rainbow in over twenty years.

Olivia:
I didn't know that.

Dunham:
As our world began to repair itself I began to imagine the people from my side would begin to see them again. You know, something so beautiful, so perfect. I still find myself looking up after it rains.
