Well, I did warn you.
Below is a picture of recent filming with David Tennant and the one and only Wilf, Donna's grandfather! This has practically confirmed the rumours that something surrounding Donna would be happening. The most likely theory is that she gets her hands on Verity Newman's new book, A Journal of Impossible Things (see older posts for info) What do you think? Could the mouthy bride be returning for one last time before Doctor Number 10 regenerates?
Thanks to 'Scootyboy' for the pictures on his Photobucket account!
