A special scene was written by Chris Chibnall that revealed some answers to Brian and The Ponds life but sadly, the sequence was never shot. However, a scene using animated storyboards and a voice-over specially recorded by Arthur Darvill was released. As good as it was, the scene really should be filmed live-action and then released on the Series 7 box set later next year!
If you also share the opinion that this scene should be filmed, please sign the petition and get the word out to all your friends and Whovians everywhere.
