S21E23 · The Twin Dilemma Part 1

Doctor questions Peri’s clothing and route

The Doctor’s post-regeneration instability manifests in sudden hostility toward Peri, who enters wearing casual unfamiliar attire. His irritation escalates into a lecture on her name’s literary origins, twisting Persian mythology to accuse her of being an alien spy. The atmosphere curdles when he physically assaults her, only breaking contact when she forces him to see himself in the mirror. His collapse reveals deep self-loathing and disorientation, while Peri’s quick thinking prevents serious harm. This moment fractures their trust further, proving their mission’s fragility before the journey to Vesta Ninety Five even begins. key_dialogue: [ DOCTOR: How did you come by a name like that? PERI: It's the diminutive of my proper name, Perpugilliam. DOCTOR: Indeed. One morn, a peri at the gate of Eden stood disconsolate. Who wrote that? DOCTOR: Of course you don't. You don't even know what a peri (pronounced peeri) is, do you, Peri? DOCTOR: And that's what you are. Thoroughly evil. DOCTOR: Well, we all know the fate of alien spies. ]
