At the Dalek Academy on Skaro, a Dalek commander is berating their scuffed up student. The commander asks; "what's the first thing you were taught?". "Daleks are the supreme rulers of the universe" his student responds. The commander continues; "and what should we never do because it always ends badly?". "Join an alliance" the student responds sheepishly. "Correct!" the commander responds angrily, before he gives the student detention and 500 lines. The student proceeds to repeatedly write "I must not trust the Sontarans" on a blackboard, as he insists: "the Cybermen were doing it as well", to which the commander screams "no excuses!"
