"Don't you think... The Doctor has a rather particular attitude towards this settlement?"
"Rather than saying he has a particular attitude towards the settlement, it's more accurate to say it's towards Number Zero... This is the first power that can completely suppress Number Zero's 'cannibalistic' desires. It's not hard to guess what the Doctor is thinking."
"We can't let the Doctor waste any more time here; Grey Iron City is still waiting for his leadership. I've heard that quite a few changes have taken place in the city during the time we've been away. Taking advantage of our absence, some people have even started rebelling against the city's rules!"
"How about... we make the decision for the Doctor? It's just a small settlement, right? We can simply snatch Number Zero back. The convoy hiding Number Zero came back, I saw it first thing this morning."
