Borough canon
Ainsley appears throughout the serial material and peripheral accounts as an unstable, shape-shifting presence. The Thacker finale drafts also call this same person Harriott, particularly around the fish-prop and containment material. The released full chat now points away from a literal transformation: Ainsley / Harriott remains a distinct controlling presence around the Frainstone Variant, while ‘the Ainsley Monster’ is best read as a finale persona and visual state used for Ainsley in the Memorial Square material.
