Ex-detective Nelson Sharkley is a tritagonist turned antagonist of the series. He pretended to be an ally of Cal, Winter and Boges, but this was a trick to find out the Ormond secrets. He also lied about not being able to see his children. He shot Cal’s uncle Rafe and later got killed after Rafe drove a bulldozer into his car while he was still in there.
- His code name is ‘Deep Water’ since sharks swim in deep water.
