Peri recognizes Earth in ruined London

Peri and the Doctor explore a derelict underground station on Ravalox, discovering a fallen Marble Arch sign that defies all known maps. As Peri insists the ruin feels like Earth, the Doctor deduces Ravalox must be Earth violently displaced across space and time. Their dialogue shifts from scientific curiosity to Peri’s devastation as she confronts the obliterated remains of London. The moment forces Peri to realize Ravalox is her own future homeworld, shattering her understanding of her past and her place in the universe. The exchange underscores the collision of intellectual revelation and personal trauma, setting the stage for Peri’s deeper reckoning with displacement and loss. key_dialogue: [ PERI: Oh, Doctor, we're on Earth aren't we? I said it felt like Earth. DOCTOR: It's in the wrong part of space for it to be your planet. Besides, according to all the record books, this is Ravalox. PERI: Well then, how do you explain this? DOCTOR: Well, they. I can't. Not yet. Unless of course, perhaps they collected railway stations. PERI: That's ridiculous. DOCTOR: But not impossible, though. Not as impossible as the other explanation. PERI: What's that? DOCTOR: Well, that somehow or other your planet and its entire constellation managed to shift itself a couple of light years across space, after which, for some reason, it became known as Ravalox. PERI: Well, what time are we in? PERI: Doctor, I know it is. I can feel it. DOCTOR: Now, don't get emotional. PERI: Don't get emotional. This cinder we're standing on is all that's left of my world. Everything I knew. ]
