Master Plans and Junkyard
The Doctor is at the Junkyard, contemplating going to see the Master when his Rose joins him. They speak about who they use to be and who they might become. Afterward, the Doctor heads off to find the Master, who has made himself a little shanty with all of his things from the TARDIS. He is mad at the Doctor, mad enough to make him cry and brush the puppyish Time Lord off.
