Written by Jeffrey Bell and directed by Bill L Norton, it was originally broadcast on October 1, 2001 on the WB network.
Wolfram & Hart lawyer Gavin Park visits to inform them of the Hyperion Hotel's building code violations.
Gavin informs Lilah that he's been moved into her department, and the two share bitter words about their approaches to dealing with Angel.
Wesley sends Angel to find the key that goes with the coin while Lorne tries to question the Powers That Be about their actions.
As a result of the man's mental efforts, Cordelia gets hit with a massive vision about fire that flings the Host across the room and burns her face and limbs.
Angel visits Lilah, who informs him that, unless he uses the key and coin to free an "unfairly imprisoned" man from a hell dimension, the physical effects of Cordy's visions will worsen.
Angel inserts the key into the coin's hole, which transports him to a hell dimension where he encounters a demon guard protecting a large fiery cube surrounding the prisoner, who is constantly aflame and in agony.
Lilah has Brain Man in the back of a limo work his magic to end Cordelia's suffering.
"That Vision Thing" was the first Angel script written by Jeffrey Bell, who went on to both write and direct many subsequent episodes.
[3][4] Makeup artist Robert Hall explains that Bell "described Skip enough for us to get a cool feeling about what he could look like, but he wasn't really restrictive."
"[5] This episode marks David Boreanaz and Charisma Carpenter's 100th appearances as Angel and Cordelia Chase respectively.
