I believe Sam Hall planned a storyline where Joe and Maggie did get together again when they found one another at Wyndcliffe.
I guess poor Sebastian Shaw got told by Maggie: "take your love beads, your patchouli, your tie-dye and your go-go boots and BEAT IT!" (thinking of the character FINALLY getting her mojo back).
Maggie was such a great character in the early days. Her "courtship" of Joe is a treat to watch--those "cat and canary" expressions of hers!
