In Mottson, at "a filling station," "they" tell Jason where the traveling show can be found (308). The novel provides no evidence about who "they" are - whether customers or attendants at the gas station, or both.
In one of the fantasies he has while driving to Mottson Jason imagines leading "a file of soldiers" to capture the sheriff who would not help him (306). While Jason's grandfather was a General in the Confederate Army, he himself never led troops, or served in any army.
Chasing his money, Jason imagines a scene in which he commandeers someone's team of mules to pull his car from the imagined mud that is trying to stop his pursuit. The team's "owner" whom he strikes down is, of course, his own invention (306).
