Sacrifice and the lyrical cruelty of survival
Every would-be escape crushes underfoot a buried moral ledger: Varne dies holding a corridor against cyber pursuit so the Doctor can reach Lytton; Flast detonates the Vastial to erase Cyber Control at the cost of her own life; Rost falls shielding the party from a rear assault. These deaths are not merely functional; they are lyric, tallying the price in human memory that the Doctor and Peri must carry away with them. The Cyber tombs become cavernous monuments to the vanishings that sustain hope, where grief is the residue of every calculation.
