Ralph says this when he has gone on legal record saying he hasn't bothered to go through the required steps to get his name on the birth certificate, and has Tweeted out saying that the financial cost of having Xander recognised as his and getting visitation rights isn't worth it.
He's literally said that having contact with his son isn't worth the cost. I'm sure Xander will love to hear about that - this Wigger is gloating about being steps ahead whilst constantly proving the point of what a useless father he is. Edit: For the people who think Ralph is a narcissist, it is worth noting that Ralph only views visitation with his son as how it impacts him and fails to consider how it could be a positive experience for his son.
Plus, how is keeping a child from the father that released revenge porn of the mother over petty internet nonsense a ridiculous idea. Ralph is an abuser, and Faith for all her faults shouldn't have to deal with that. I don't think Xander will ever see Ralph, not as a father anyway - maybe he'll visit his sibling, but tbh Ralph shouldn't expect to be a live in dad with May anyway.
Do we even give Ralph another 18 years to live? Ronnie was in much better shape than Ralph and died at 64. Ralph is a complete mess physically, and has multiple addictions, is incredibly stressed and is a fat fuck - he'll be mid-fifties by the time Xander might come see him. He's probably just gonna be a bum at that point the way things are going, or more likely dead.
