Trumpkin doesn’t believe in what he can’t see; because the trees have been asleep for nearly as long as Aslan has been absent, he discounts Trufflehunter’s words as fairy tales. He believes in what he can see: Telmarine abuses and Old Narnians in hiding. This suggests that the right evidence might awaken his faith. Notably, as the Old Narnians gather, they naturally welcome Caspian into their ranks, confirming his fitness to rule. Only Nikabrik holds himself separate from the rest of the allied Old Narnian forces.
