Peri calls on Kamelion to break free

Frustrated by the deadlock with the Master in Kamelion’s guise, Peri seizes on the alien robot’s lingering autonomy. She implores Kamelion to shed the puppet identity and reclaim its true self, pleading for visible proof of its hidden power as the planet groans toward cataclysm. In the hush of that plea she forces Kamelion to confront its past servitude, gambling that the dormant alien can still answer. The moment refracts the season’s larger themes of control and identity, positioning Kamelion’s transformation as a last, desperate thread in the tapestry of escape. key_dialogue: [ PERI: Kamelion! Where are you, Kamelion? Come on, show me your real self. Come on! PERI: Yes, Kamelion, your real self. Come on. If you can't manage that, show me Howard, please! ]
