In recent posts, I've discussed some of the influences on my 1930s flyboy character, C.J. Stone, protagonist of my ebook collection, Stones. Another influence was Jack Dalton (Bruce McGill), a childhood friend of MacGyver's, who first appeared in the Season 2 episode, "Jack of Lies".
In the episode, Jack steals all of MacGyver's belongings to rope him into flying to South America to rescue fellow friend Mike Forrester (Patricia McPherson). Dalton was like a big kid, thrilled with adventure but always in over his head. He was also an inveterate liar, but Mac could always tell when he was lying because his left eye twitched.
C.J. is more mature and a better liar, but he still prefers adventure to boredom, as seen in the BEAT to a PULP story "Artifacts".
