 What is Trella's relationship to Dom Blessing?
Trella feared she was in for trouble even before Motwick's head dropped forward on his arms in a drunken stupor. Perhaps she could call one of Motwick's friends; she had no one on Ganymede she could call a real friend herself. Trella swung with her whole body, and slapped him so hard he nearly fell from his chair. The dark man moved in on Trella again as Kregg overtook his quarry and swung a huge fist like a sledgehammer. Exactly what happened, Trella wasn't sure. The dark man, who had grabbed Trella's arm, released her and ran for the door. Trella ran to the unconscious Motwick's side. He followed Trella out the door of the Golden Satellite and fell in step beside her.
