Forrest was working as a safe-cracker for Calamity before his death in 1967.
When Big Bad Mama shot Forrest for mouthing off, Big Bad Daddy was upset but he couldn't do anything about it as Big Bad Mama was the person really wearing the pants in the family. The death of Forrest shocked two Scientists working at the H.A.R.M. Rocket launch facility located on an island off the coast of Mandaru. Cate Archer overheard the conversation as she was sneaking into the facility.
