I just had a thought, set the scenario AF5 have the prisoner be the member of the Security Council deposed in the Coup (I think AF3) can't make the guy a martyr by killing him, to many friends to frame & put him on trial. So he's kept masked sedated and fed intravenously in a max security prison. Guards and inmates assume he's some super dangerous spy or some such. Revolutionaries want him because he could/does know where some Jovian military assets are, and possibly access codes. Or is that too over the top?
