Farscape S01E19 - Nerve

Crichton and Chiana try to infiltrate a Peacekeeper base to get a vital tissue graft for Aeryn, who will die without it. Crichton gets caught by Scorpius and imprisoned. He is tortured using a device called the 'Aurora Chair' which is able to look inside his mind and, as Scorpius wants, to reveal the secrets of wormholes.
