Peter Kelsey, Mark Wynn, Charlotte Elwes, Frances Webb, Cythy Alford, Miles Hadrill The Crystal Maze : Season 1 Episode 12

The Twelfth Episode. Buying out a 'locked-in' contestant required a team member to physically take a crystal to the chamber where the contestant was locked in, leaving the crystal there in exchange for their 'bought-out' team-mate. If the team had since moved one or more zones further in their journey around the maze, this buying-out was represented[2] as a lengthy trip back through the maze that effectively took a second contestant out of action for at least one game. If both the captain and vice-captain were locked in, a new captain would be elected on the spot, although this never actually happened.
