Dramatic send-off for Doctor Who companions Amy and Rory

It's the beginning of the end for Amy and Rory, played by Karen Gillan and Arthur Darvill, as Doctor Who returns this weekend.

This is the pair's last series, but we've been promised a dramatic send off.

But before all that the Doctor, played by Matt Smith, has to face some old enemies.
