Week 6 Seminar: Spin-off Drift

A spin-off starts with its parent's continuity and a licence to leave it. How far it goes, and whether the bible should stop it.

14 April 2027

The technique

Spin-off drift is the distance between what a spin-off inherits and what it becomes. Some drift is the point: a spin-off exists to do what its parent can’t. The engineering question is which rules it may leave behind, and who decided.

The case: Beebo

DC’s Legends of Tomorrow launched in 2016 out of Arrow and The Flash, as a team of minor heroes chasing an immortal villain through time. Its third season ends, in 2018, with a giant blue toy called Beebo fighting a demon. Nothing in the first season forbids it, and nothing in Arrow allows it. The show found its audience in exactly that gap.

In the seminar

We diagnose the drift the way the Retcon Proposal’s first section does: find where it starts, and classify it. Is it drift, or a new continuity wearing the old one’s cast? Then we write the bible rule that would have allowed Beebo on purpose.

Learning outcomes

This seminar works towards:

  1. Diagnose a continuity failure in a shared universe: locate it, classify it, and trace the production decision that caused it.
  2. Build a continuity bible that lets a stranger write into an original universe without contradicting it.

What to bring

Have these done before the seminar starts.
