Doctor demands clone as Leela falls back

The Doctor presses Professor Marius for an immediate cloning procedure to create a contingency host should the Nucleus fully infect him. With the mind-controlling organism tightening its grip on the Bi-Al Foundation, Marius reluctantly agrees to the Kilbracken technique despite its theoretical limitations. Leela bursts into the Isolation Ward while retreating from gunfire, informing the Doctor they have run out of ammunition and can no longer hold back the infected staff. Outside pressure accelerates as the Doctor secures his backup plan while Leela brings desperate news of total containment failure.

Key Dialogue

"K9: Replicants do not maintain their existence for long because of possible unsolved psychic stress problems."
"DOCTOR: How long? How long?"
"K9: Longest recorded clone life, ten mi"
"MARIUS: Ten minutes, fifty five seconds."
"DOCTOR: Professor Marius, could you clone me?"
"MARIUS: Certainly. The Kilbracken technique is very simple. But it's a circus trick. It's of no medical value."
"DOCTOR: Could you clone me now?"
"MARIUS: Now?"
"DOCTOR: (Outside, Leela throws her knife behind her. Lowe sends Cruikshank and Hedges the wrong way and she rolls head over heels into the isolation ward.) Yes. Because if you don't clone me now and the virus gets to me, it'll take the whole centre with it."
"LEELA: Can't hold them off any more. Out of ammunition."
