Don't get your hopes up for jail time. He'll probably walk because of the video Faith made where she said she consented.
What's more likely is that he's going to end up spending thousands of dollars on legal expenses. Six months at least dealing with these charges. By that time, the baby will be born, and it will naturally evolve into child support claims. That's when it gets really fun, because he's a wigger and loves talking about his money. He claims he makes thousands of dollars a week and will have to support those claims in court (making his financials public record and increasing his own child support burden), or try and walk them back and plead poverty, which will shatter his ego and cause him to start lashing out again.
Ralph is at his least interesting when he's under duress. He's going to act sober and listen to his attorney. When he wins his court case, he'll go full retard again and harder than we've seen. Reality will catch up with him again during the child support saga and that will also be funny.
That's the thing about Ralph. He loves talking about how he's a heel, but this is the reality of being the bad guy. Ralph wants to be Lex Luthor and people want to jeer him because he's fat and contemptible. He's playing a high-stakes, no-win game where his only condition for failure is not being able to do his podcast and drink himself to sleep. As long as he can keep doing that, he's a living, breathing soap opera broadcasted for everyone to watch.
