The old truck in which Kimble and Sister Veronica traveled in "Only Angels Travel on Lonely Roads" is seen parked in the school garage.
The ailment Sr. Veronica suffers is a parasagittal astrocytoma, which is a malignant tumor generally located toward the middle region of the brain near the surface.
Bill Raisch as one-armed man Fred Johnson appears both in the main title sequence and also in a photo Kimble provides in requesting Sister Veronica's help.
The car that Sister Veronica drives is a 1961 Plymouth Valiant V-200.
The footage where Kimble jumps on a freight train while chased by policemen was previously used in S4E10, "Nobody Loses All the Time"
