Before: Secure in its holder, likely in the Rani’s possession or on display in the lab.

After: Held aloft by the Master, its contents sloshing as he taunts the Doctor and Peri, now a tool of intimidation.

Peri reveals botanical gap Ravensworth fills

The Doctor’s sleeping draught remains a theoretical solution only; Peri’s admission of ignorance forces the draught’s immediate utility into doubt. Held by the Doctor in a small vial, its potential efficacy now hinges on Ravensworth’s volunteered botanical input, becoming a shared project rather than a ready tool.

Before: Possessed by the Doctor in a small glass vial, secure and untested

After: Still in the Doctor’s possession but its application delayed, now contingent on Peri and Ravensworth identifying appropriate herbs

Peri calls out the Doctor's oversight about the TARDIS

The glass vial containing the Master’s hypnotic draught is prominently presented by the Doctor as proof of his successful theft, functioning as both a strategic asset and a symbol of his tactical maneuver. Peri’s immediate seizure of the vial to deliver it to Ravensworth signifies its transfer into external operational use, removing it from the Doctor’s direct control.

Before: In the Doctor’s possession, secured through sleight of hand during a confrontation with the Master.

After: Transferred to Peri for delivery to Lord Ravensworth as part of their attempted countermeasure.
