Peri recognizes Earths ruins as her home

Peri’s composure fractures when the Doctor identifies the abandoned underground station as a fragment of Earth’s future self, Ravalox. Scientific speculation gives way to raw recognition as Peri senses the devastated continent beneath her feet is London, the ruined totem of her birthworld. The Doctor’s clinical observation about temporal displacement collides with her visceral grief, exposing the personal cost of cosmic displacement. Her fragile hold on identity unravels in the face of two billion years of desolation, forcing Peri to acknowledge home as ash and memory. key_dialogue: [ PERI: Oh, Doctor, we're on Earth aren't we? I said it felt like Earth. DOCTOR: Well, that's another billion to one chance. It does begin to seem a little unlikely, doesn't it? PERI: So what happened to London? DOCTOR: Wiped out, if this was London. PERI: Doctor, I know it is. I can feel it. PERI: Don't get emotional. This cinder we're standing on is all that's left of my world. Everything I knew. ]
