Part 4 of 6! The legendary Doctor Who is back! The Doctor is currently the Tenth Doctor, the last of the Time Lords, survivor of a Great Time War and, along with his loyal friend and companion Martha Jones from London, they stop oppression, darkness, and evil spreading throughout the galaxies. They're also on the hunt for the best chocolate milkshakes in the cosmos... and while they track that down, someone else has the Doctor in their sights. As the very last Time Lord out there, he's highly collectable, to the right people!
