Brand new Tennant-Smith Doctor Who pic reveals intriguing guest star

A second Doctor Who 50th anniversary read-through pic with the 10th (David Tennant) and 11th (Matt Smith) Doctors reunited again has emerged, this time with a new guest star in tow.

While we’re still trying to recover from the epic awesomeness that was yesterday’s pic—setting many a fan’s heart aflutter—a second pic includes not only Jenna-Louise Coleman, who plays Eleven’s companion Clara, but also a brand-new guest star.

The blond lady beside Tennant is Gavin & Stacey’s Joanna Page, who was rumored to have a part in Doctor Who a few years back. Perhaps this time she could be playing the Doctor's granddaughter Susan? This is simply speculation on our part, since the role Page will be playing has not been revealed.

What role do you think Joanna Page could play in the upcoming Doctor Who 50th anniversary?
