[1] Written by Darrick Bachman and Genndy Tartakovsky[2] and directed by the latter, in a "detour"[3] from the story of Spear and Fang, the episode pivots to follow Charles Darwin (Jacob Dudman) and C. D. Darlington (Jeremy Crutchley) as their discussion of evolution is interrupted by an escaped inmate (Fred Tatasciore).
[4] The first episode of the series not to feature Spear or Fang, it received critical acclaim, and was followed by "Vidarr", returning to the duo's storyline, releasing to home media on April 25, 2023.
Charles surmises that, in the right situation, any person would regress back to their primitive roots in order to survive, which Darlington dismisses as lunacy.
The evening is cut short when an escaped inmate (Tatasciore) from a nearby asylum — who heavily resembles Spear in silhouette — breaks into the house, kills the butler Stevens (Dudman), and proceeds to prey on every person inside; including Giroud and Bertie.
In the ensuing fight, Blakely is eventually knocked out by the inmate before Charles and Darlington gain the upper hand.
