Doctor Who: Every Single BAD WOLF Easter Egg And Reference

20. The Bad Wolf Scenario (The End Of The World)

Back when Russell T Davies was a master at seeding these references into the background of his episodes, in a way that you’d only ever notice them on a rewatch, most people won’t have given this line a second thought until revisiting this episode after watching the finale.

About half way through the episode, right at the start of the scene where the Doctor gives googly eyes to a tree, as the camera pans across the room, we can hear the Moxx of Balhoon saying “Indubitably, this is the Bad Wolf scenario” to the Face of Boe.

What does this mean? What is the Bad Wolf scenario? Does Russell even have an answer? Who knows! But it’s a fun start to these two words being seeded throughout the Doctor and Rose's lives.
