Ryan Weller is an agent with DWR.
Once it is established that the acronym stands for Dark Water Research and that it is legally an American commercial dive and salvage company, it would seem more appropriate to say he was an employee than operative but there is a bit more to DWR than is normally mentioned in any earnings statement.
On paper DWR, established during World War II, "had grown from a two-person shop to a worldwide conglomerate. It provided a wide range of inspection, design, and maintenance services, from in-water ship repairs to underwater construction, but its bread and butter was the oil service industry." It currently operates just north of Galveston and when we first learn of it, its new CEO was Greg Olsen, son of the previous leader and an EOD expert who was now confined to a wheelchair since "shrapnel from an IED had severed is spinal cord". He assumed the lead position after his parents were killed in a terrorist attack.
In addition to its many overt projects, "as DWR had expanded, the company had worked alongside the government on maritime security issues in and around the waters of the United States, before being asked to run clandestine operations on their behalf." For several decades now, a good part of the company's income came from hush-hush underwater missions brought to it by the DOD and DHS. With the two previous CEO's being former SEALs, underwater demolition work, both offensive and defensive, came natural. With DHS calling with a new mission, a replacement EOD man was needed and that is how Weller is brought in.
Six-foot-tall Weller, with "wide shoulders and a narrow waist" and muscles "hardened and strengthened [by] years of constant physical exercise", is a native of Wilmington, NC. Though the family business was home construction, his love of the water had been with him since his youth and his purchase of a Sabre 36 sailboat in terrible shape which he and his father had reconditioned.
Weller served in the Navy in the Explosive Ordinance Disposal division for over ten years, the last couple in the arid land-locked Afghanistan where he was severely injured in an enemy attack. He was shot twice and saw his best friend, the Olsen mentioned above, nearly killed. Since that event, Weller has returned to civilian life but still has to deal with recurring PTSD.
Despite that problem, though, Weller is, when we meet him, in need of adventure. When the offer from DWR came, it did not take him long to say yes.
