Doctor destroys Omega on the pier

Omega attempts a final, desperate transfer by hijacking the Doctor’s form but fails as the bond is unstable. The resulting anti-matter explosion devastates the craft, forcing Omega to flee Earth with his consciousness tenuously bound to a stolen form. The Doctor seizes the Ergon’s matter converter weapon, realizing he must now destroy Omega permanently before Gallifrey faces irreversible annihilation. The moment cements his resolve to eradicate the threat entirely, shifting the conflict from containment to annihilation.
