On Wednesday there was a live-stream interview with Edward Kitsis and Adam Horowitz. It was a great interview but the best part was a 3 minute clip at the beginning from the prelude episode.
The only problem is that the dialogue is dropped real low in the clip for some reason (this does let the music come through more though and it's awesome
Enjoy.
