We watch the 13th episode titled "The Parting of the Ways" (Series 1, Episode 13), the third part of the "Long Game" trilogy (now without even more albino Simon Pegg!). Where Rose tries to impress the Doctor by learning how to fly the TARDIS and save him from certain death in the form of giant pepper pots. Spoiler alert: she doesn't. It's the end... but the moment has been prepared for.
