Edit: I think I just recalled something. Joe P had nothing to do with looking for Abyss per se. He was looking for his brother---Chris who incidently played the roll of Abyss. He came in as a concerned family member, asserting that Chris may been the victim of foul play "in real life"---So, he began his investigation for his brother, Chris, by first checking out his place of employment for clues into his disappearance.
Since, Joe works/owns Park, Park, and Parks law firm--Would they introduce more of his family law practice folks into a Joe Parks stable? Cheesy Gold.
