Coronic Acid Canisters

A reserve of three small metal canisters containing coronic acid, a clear, odorless liquid chemical weapon. The canisters are etched with cuneiform-like hazard warnings, their valves taped shut to indicate recent handling. Chessene conceals this reserve undetected against the possibility of Sontaran betrayal, intending to deploy the acid to wipe out Stike's forces should her alliance with Dastari fail. The Second Doctor handles these canisters with deliberate care in the cellar, underscoring their volatility and strategic importance.

S22E9 · The Two Doctors Part 3

Shockeye awakens to Chessene's betrayal

Coronic acid is referenced by Chessene earlier as a contingency weapon intended to eliminate the Sontarans, but its presence is off-screen. This plot device underpins Shockeye’s fury—his discovery that Chessene planned to murder allies without his knowledge or consent.

Before: Three canisters were prepared prior to leaving the station and concealed by Chessene—likely stashed within the cellar or carried unseen.

After: The acid remains hidden, its potential unleashed only if Chessene or Dastari’s plan fails, maintaining its threat as an unseen catalyst in the room's tension.
