Doctor reveals containment plan to Colby

The Doctor and his companions face the Fendahl’s imminent transformation, scrambling to prevent its completion. Colby arrives with a critical lead-lined box, which the Doctor immediately identifies as the key to containment. Revealing a high-risk plan, the Doctor tasks Colby with operating a scanner beam to disorient the entity long enough to retrieve the skull. A controlled implosion triggered three minutes after the scanner’s deactivation will ensure the Fendahl’s destruction and the priory’s obliteration. Urgency permeates the exchange, as the Doctor balances desperation with precision, underscoring the stakes of failure while rallying their unlikely ally against an unstoppable force.

Key Dialogue

"COLBY: Oh, where are you going?"
"DOCTOR: Lead lined?"
"COLBY: Yes."
"DOCTOR: Perfect. Right, now this is what I want you to do. Give Leela and me time to get down to the cellar, and then switch on the scanner beam. With luck it should confuse things down there long enough for us to grab the skull and get away."
