What happens
Jerry Hall and Joan are held aboard an Euclidian submarine under Commander S1, who keeps them in check with magnetic paint and close watch. Jerry chats with Joan about the commander, and the commander warns them both to keep quiet. The submarine is approaching Johnson's boat, and S1 has Jerry speak to Johnson by radio to confirm his position and speed. Jerry is told to reassure Johnson that all is well, but he is not allowed to say more. Captain Bradford's materials and the scientific apparatus are still on board Johnson's boat, and the commander plans to take the vessel to Euclidea.

Written from the episode itself; it never gives away the ending. Every recording is remastered for the stream: cleaned of rumble, hiss and mains hum (and the old TV whine where we found it), then levelled in two passes to steady broadcast loudness, so one show is never quieter than the next.
