We’re sure you were all left screaming at your TV screens following Carmen’s warning at the end of Planet of the Dead, and while the nation waits in agony for the Tenth Doctor’s final moments, and to discover the truth behind the chilling prophecy, we’d like to hear some of YOUR theories about who – or what – is about to make an untimely return from out of the darkness…

This is Doctor Who we’re talking about, and while all the signs are pointing at the obvious (tap-tap-tap-tap!), no doubt Russell T Davies will have thrown a spanner in the works and is sitting on his throne in Cardiff enjoying a latte (whilst stroking his beard in a menacing sort of way) as Whovians across the land speculate and plot and scheme the remaining nights away.

Feel free to share your thoughts below, but please be aware that this discussion is a spoiler zone so don’t read any of the posts if you don’t want to be spoiled!
