It's kind of funny how Landon realizes too late that he's the only sane person in this whole circle of people. (I guess Maggie would have been the other one, but of course Veronica casually took care of that!) Landon might have felt that Jeffery was...salvageable? Like maybe he needed to be rescued from his family situation by Landon the Hero. It took him a while to realize that Jeffery was/is part of the whole landscape and doesn't seem to want to be 'saved'. Jeffery's continued devotion to Wyatt (or the idea of Wyatt, actually) continues to grate on my nerves, but it is realistic that Jeffery would back off from a genuine guy like Landon in favor of an unavailable man like Wyatt, since he's still not confident in his ability to have a normal, healthy relationship. Mooning over Wyatt was/is "safe". I guess married, deeply-closeted Officer Justin is the next best thing, since he's unavailable (except for booty calls, etc.) and wants to stay that way. If Jeffery had been able to go from Wyatt (unrequited love) to Justin (casual sex) to Landon (actual love), it would have been a healthier progression.
BTW, the whole "Justin's wife is the judge in Veronica's case" was a plot point they threw in at first but did not follow up on properly, and actually they barely mention the wife again, much less her connections. I can't even recall her name! Pearl mentions in passing that her son is a policeman and that her son-in-law is the Chief of Police, but that was also never mentioned again (as of the last episode I watched). She didn't mention her daughter-in-law was a judge (something a name-dropper like Pearl would mention).
The police department, jail adminstrators, and social workers in their version of Savannah sure are inept, aren't they? When they're needed to investigate crime scenes, they overlook the simplest details. But that's soap for you.
