Colonel Charlie Watts is a soldier for the Nationalists of Terra. He has performed special missions for General Maxwell and President Arends. At some point he was captured by the Eastern Alliance, and is currently presumed to be held prisoner on Lunar One.
John has Apollo assume Charlie's identity in order to attempt to convince the Terrans to avoid an impending nuclear holocaust. Apollo is greeted on Terra by Brenda Maxwell, who apparently has been romantically involved with Charlie Watts (prior to his capture). "Charlie"'s erratic behavior prompts Brenda to contact Nationalist security forces, and Apollo is apprehended (Experiment in Terra).
Notes
- This "part" was evidently for Starbuck (Dirk Benedict), however this episode was an "Apollo episode", because Richard Hatch rightly felt that his character was being pushed to the side.
