1. Martian Code

She runs frantically around trying to reverse the destination of the Tardis but to no avail. She flings open the door and finds herself on a street corner in London with her friend, Mickey, running toward her. He says that he heard the engines of the Tardis as it landed and knew there was nothing else that it could be. Rose falls into his arms weeping.

Meanwhile, back on the space station, Capt. Harkness asks the Doctor if he really plans to destroy everyone on Earth and in the space station in order to stop the Daleks from taking over the universe. The Doctor says “Die as a human or live as a Dalek – what would you do?”

Rose is devastated at being sent home. She tells Mickey and her mom, Jackie, that she has to get back to the Doctor and runs out of the diner where they are having lunch. She and Mickey walk the streets until Rose find some graffiti on the walls that are spray-painted “Bad Wolf”, a phrase that she’s seen here and there in her travels with the Doctor. She wonders if it isn’t placed there as a sign of hope instead of one of dread.

Harkness and the Doctor continue to fight the Daleks while Mickey tries to convince Rose to stay home and forget about the Doctor. I’ve always felt sorry for Mickey, he’s seem some of what Rose has seen with the Doctor but he chooses not to save the universe. Just as Rose is sure she’ll never see the Doctor again, Jackie shows up with a gigantic truck to help Rose open the heart of the Tardis so Rose can communicate with it.

Meanwhile the fight goes on with the Daleks and Earth and all humans on the satellite ship appear to be doomed.

Mickey has chained the truck to the engine of the Tardis, trying to open it up for Rose. Just as it opens, the door closes with Rose inside and she is able to connect with the heart of the Tardis, absorbing the power that was never meant for a human to tap. As she starts to glow with power, she controls the Tardis and is able to take the return course back to the Doctor.

The Daleks are killing the courageous group led by Capt. Harkness and Jack himself is downed. The Doctor has finally constructed a controller that should destroy them all: Daleks, Earth, and the ship with everyone in it. The head Dalek asks “What are you: coward or killer?” and the Doctor has to admit he cannot exterminate them all. Just at that moment, Rose returns and emerges from the Tardis, glowing with power. The Doctor warns her that she will surely die, but she feels all powerful, she begins to kill some of the Daleks one by one, followed by destroying some of their ships one by one. She is able to bring Jack Harkness back from the dead before she gets to a point where the power is too much for her.

The Doctor knows she has met her match and he takes her in his arms and kisses her as the power transfers to him and Rose faints. The Doctor takes her into the Tardis and, when Rose comes around, his body convulses as it starts to die. He tells her that his kind has a way of cheating death, but that he will change into something else. His last words to Rose are “You were fantastic…absolutely fantastic. And you know what? So was I!” His body then violently morphs into the new Doctor Who and he looks at Rose, moves his tongue over his lips and says, “New teeth – that’s weird!”

And thus ends the first new series of Doctor Who.
