Bad Wolf

Two words turn up on a wall in 2005, on a poster in 1987, on the side of a helicopter, in Gallifreyan on the door of the TARDIS. Rose Tyler spends thirteen episodes walking past her own message without reading it.

This is series one in broadcast order, which is also the order the words appear in. The pay-off only lands in sequence, so start at the shop dummies.

2. The End of the WorldS1E2. Five billion years out, and the first time the words appear.
3. The Unquiet DeadS1E3. Dickens, Cardiff, and the Gelth.
4. Aliens of LondonS1E4. First contact, and Rose has been gone a year.
5. World War ThreeS1E5. Downing Street, and a missile aimed at a house with Rose in it.
6. DalekS1E6. One survivor, one cage, and the Doctor at his worst.
7. The Long GameS1E7. Satellite Five. Keep it in mind for episode twelve.
8. Father’s DayS1E8. Rose breaks the one rule.
9. The Empty ChildS1E9. The Blitz, a gas mask, and a boy asking for his mummy.
10. The Doctor DancesS1E10. Everybody lives.
11. Boom TownS1E11. Dinner with a condemned prisoner.
12. Bad WolfS1E12. Back on Satellite Five, and the words are the name of the station.
13. The Parting of the WaysS1E13. Rose looks into the heart of the TARDIS and scatters the words herself.
