Doctor fails to save infected Chase from compost machine

Chase, infected by the Krynoid and its zeitgeist of dominion, attempts to sacrifice Sarah Jane to the compost machine as part of his twisted devotion. The Doctor intervenes just as Sarah awakens, violently shoving Chase aside to turn off the machine. But Chase’s obsession persists—he activates it again, trapping the Doctor who barely escapes as Chase is pulled into the shredder. The horror of the moment collapses into the Doctor assisting Sarah, then carrying her from the room as she sobs over Chase’s death. This marks a moral reckoning for the Doctor, who tried to save even a monster, while Sarah grapples with the brutality of their fight for survival against the spreading Krynoid threat.
