Omega’s desperate final stand crumbles

Omega makes a last-ditch attempt to seize the Doctor’s form under the guise of transfer, only to reveal his stolen flesh then crumbles into bluster when Gallifrey’s fusion booster explodes from sabotage. The Doctor warns of the bond’s failure even as the room fills with red light and collapsing debris, forcing Tegan to duck for cover. Omega’s hubris is exposed as his glowing pseudo-skin tears away to his true decaying face, his boast of rebuilt power unraveling into desperate pleas to live. When Gallifrey’s shadow looms over his escape path, the Doctor races to salvage the matter converter, leaving Tegan to choose between Colin’s recovery and continuing the fight.
