Getting back to Matt/Kimber story line. At least they had a plausible reason to end up in Cali since they were meth users and needed to suck on the teat (Sean and Christian) that could keep them afloat financially. But Liz, Linda, Annie and Julia just didn't make sense in a real world scenario. But I'm glad that they ended up there because to just drop them for the sake of "keeping it real" would have wrecked the series as you pointed out.
