Honestly, at this point I wonder what WOULD happen if Rudy told his parents that he is a reincarnated guy from another dimension. The time they'd spent up until now has been mostly genuine, Rudy isn't that much of an actor, he went with the flow.

I hope that is something that happens at some point. Maybe it'll be a tragic incident, but Rudy should be confident and strong enough by then to accept the consequences. And really, none of this is his fault.
