TARDIS arrival at infected Titan Base

The Doctor dematerializes the Titan Base distress call as the TARDIS rematerializes in the solar system between Jupiter and Saturn in 5000 AD. Leela examines the sleek new console room but notices the time rotor stop and viewscreen activate, revealing their location near Titan Base. The Doctor explains that humanity’s expansion into the solar system—an era of pioneers spreading across the galaxy—echoes his earlier metaphor of disease, hinting at an unseen cosmic threat that soon confirms itself when Safran’s corrupted voice breaks through the distress call. This moment marks the transition from calm reassessment to the battle they now face. key_dialogue: [ DOCTOR: Yes, between Jupiter and Saturn. About five thousand AD. Five thousand AD? We're still in the time of your ancestors. LEELA: Ancestors? DOCTOR: Yes. That was the year of the great breakout. LEELA: The great what? DOCTOR: Mmm. When your forefathers went leapfrogging across the solar system on their way to the stars. Asteroid belt's probably teeming with them now. New frontiersmen, pioneers waiting to spread across the galaxy like a tidal wave. Or a disease. LEELA: Why disease? I thought you liked humanity? DOCTOR: Oh, I do, I do. Some of my best friends are humans. When they get together in great numbers, other lifeforms sometimes suffer. ]
