As I see it, Lloyd has a grace deficit disorder. He will never be happy until he learns to deal with that. Up to the time that Nicholas showed up, Angela and Jeremy worked well with Lloyd, and appreciated what he did at the station. They didn't have the full story on Nic's actions and went into default mode as parents. Lloyd, in his way, has been as underhanded as Nic. Anybody who slights Lloyd is punished. He doesn't work to make things right or build around problems with other people. Look at the short story arc with the receptionist in the office in Perth. You cross Lloyd, and you'll get yours. To start writing in things to make Angela and Jeremy suddenly become different people than they were earlier in the story would be disingenuous. Until he truly makes things right with Angela and Jeremy, he's a dick as much as Nic.
