* Although ''Highway to Heaven'' was pretty, well, blah from an action viewpoint, the episode "Plane Death" featured Jonathan confronting men who'd killed Mark's friend for money; when they not only showed no remorse but also decided to kill him and Mark too, he went from mild-mannered helpful angel to Terminator, shrugging off punches, chair shots, and ''shotgun blasts'' with an emotionless face and throwing a few of the men across the room with one arm. When one panicked and confessed to the crime, he found Jonathan had vanished mid-confession... just in time for the ringleader's father, and the cops, to show up.
