The Doctor From Gallifrey 

WARNING: CONTAINS SPOILERS, DO NOT READ IF YOU DON'T WANT TO KNOW WHAT HAPPENS!

Neil Gaimon's masterpiece saw the Doctor recieving a message from a Time Lord who was apparently outside of the universe. On arrival the TARDIS' soul is put into a woman and it appears that the message was not from a living Time Lord but a message from a dead one. The asteroid they land on has a consious and is known as "House" who feeds of the energy of TARDIS'. When House learns that the Doctor's TARDIS is the last one in existence he steals it with Amy and Rory inside. He heads towards the universe and the Doctor and Idris have to build a TARDIS out of scrap to catch up. They land in the old control room only and House tries to kill them by deleting the room. They are transported to the main control room and the TARDIS leaves the body of Idris and returns to where it belongs, where it destroys House.

All in all, it was fantastic. The Doctor's relationship with the TARDIS became much stronger. We have always known that the TARDIS is a living thing rather than a machine but this episode took it into new territory. Surranne Jones was fantastic as Idris as was Micheal Sheen as the voice of House. Plus I liked seeing the TARDIS corridors and seeing the old control room one more time.

There was another bit of mystery with the TARDIS looking into the future and saying "The only water in the wood is the river". One presumes she means River Song. And the only issue I had was Rory being killed again, albeit it briefly this time. Rory is quickly catching up with the daleks in the number of times he has been wiped out but still comes back. But apart from that is was a cracking episode that fans will truly have loved!
