Quentin Watson II
Bombardier Quentin Watson II was a former ship-mate (and thus family) of Theo's, from before the survey ship Fisgard was seized.
He is a pudgy imperialist-type character who likes large-bore rifles and Civilized Space War.
Because it took over a year for the ship to be returned from Abaslom impound, many crew had to find jobs elsewhere; the Bombardier was one of them. A few months into the affair, Theo lost track of him.
It's likely that Watson has fallen in with a Bad Crowd so he can take advantage of his combat proficiency. His new role in life would be something like security / debt collection / "fixing".
He's a fan of spacegin, interventionist foreign policy, drawing arbitrary borders, a bit of casual racism, and wanton violence (at a distance)! He's also likely quite bitter with the Absalom authorities for taking his home away and forcing him to start over.
Quentin served as security chief at the Trucs Bout à Bout, and played an active role in the Trucs Bout à Bout Incident.
