S16E17 · The Power of Kroll Part 1

Doctor risks safety to stop human retaliation

The Doctor learns the Swampies are preparing a blood sacrifice to their deity Kroll and realizes Romana is the intended victim. Despite Thawn’s threats and urgent plans for a violent retaliatory strike with gas mortars against the settlement, the Doctor refuses to abandon Romana. He dismisses Thawn’s dismissive warnings that he cannot cross the swamps alone and prioritizes saving Romana over self-preservation, confirming his moral opposition to Thawn’s aggressive colonial agenda and escalating the physical confrontation between human colonizers and native Swampies. key_dialogue: [ MENSCH: My people are calling Kroll. They're making a blood sacrifice. DOCTOR: Who's Kroll? THAWN: Oh, it's their name for a giant squid. Centuries ago, when we resettled the Swampies from Delta Magna, we shipped along a couple of specimens just to keep them happy. DOCTOR: Yes, but just the same, a blood sacrifice. I don't like the sound of that. THAWN: Don't be stupid. You'll never cross those swamps on your own. ]
