Speaking to press ahead of the launch of Ghosts season 5, co-creator and star Mathew Baynton said: "It’s fair to say there’s a couple of backstories that the audience will have been waiting for.

“There are still some unsolved mysteries and this is the final series – and we wouldn’t leave our audience with those unanswered questions.”

Willbond later confirmed that The Captain’s story is one such arc that will see some long-awaited resolution.
