Doctor forces Morbius into deadly psychic duel

The Doctor goads Morbius into a lethal mind-bending contest to halt his genocidal rampage. Their duel of past incarnations strips Morbius bare of Time Lord pretensions, revealing a mind corroded by Solon’s crude revival. The Doctor’s taunts push the unstable Time Lord beyond endurance, triggering a catastrophic psychic collapse that leaves Morbius broken and fleeing. Yet the victory costs the Doctor dearly, collapsing from his own injuries as Sarah scrambles to save him before the Sisterhood arrives to finish off Morbius.
