After observing Dorian, he reached this conclusion, which implied that...
In Dorian's hands, his own little life was very unstable.
Dorian believed the nonsense he had spouted earlier, thinking that there was an organization in Scameroon that worshipped Mad Fire, and he joyfully headed this way, claiming he wanted to join and contribute to the organization.
But Todd knew that there was no such organization; he had only learned about Mad Fire by accidentally seeing a newspaper from Warrior Country, most people didn't know about it at all, let alone have organized faith.
So, when Dorian arrived in Scameroon and found there was no such organization, his little life was doomed.
To prevent that from happening, Todd tossed and turned on sleepless nights during the journey, contemplating multiple plans.
He had told Dorian to find research on Mad Fire when he was in Warrior Country, claiming he wanted to study and understand Mad Fire more deeply, and Dorian indeed found it for him.
