When it comes to sped family members, unfortunately, some family members choose to shun them once the parents pass away. This is pretty common amongst families that chose not to reign in their tards and let them run amok. Family members would tolerate them outta respect for the parents.It's very troubling when you have a family member that relies on you for day-to-day survival. Russ is clearly capable of going out and getting a job, but I imagine his parents are worried about his behavior after they've passed and there is no one left to keep him in check. I don't know what it takes to not love your own child, but it doesn't take much to worry about them. Clearly they won't be able to leave him much because he'll just fritter it away on lawsuits and backstage passes. I only hope when they do pass that he has enough self-restraint that his sister doesn't need to tell him "Don't come to the funeral if you're going to talk about your Taylor Swift crap."
Rusty seems like one of those cases, especially since they couldn't even have him at his own sister's wedding. They will probably leave him with inheritance that will most likely be controlled by his sister or another member.
