Synopsis for "The Dark Side of Evil"
Jack returns to his apartment to find he's being evicted. Buck puts him up and offers a possible solution to the werewolf problem -- the work of a scientist that's been making a real life version of the Jekyll/Hyde formula. Hoping to find a way to isolate his bestial side, Jack goes with Buck to visit the scientist. Unfortunately, the scientist has accidentally tested the wrong formula and become a rampaging evil monster calling himself DePrayve. The Werewolf and DePrayve fight through the streets and in the end DePrayve gets away while the Werewolf gets captured by the police.
