My theory is that Dirk will become the new Kids' "Lord English" and he will be the one they have to defeat to create a new world. I think Dirk believes he is 100% in control of everything because he thinks he's "above" the narrative. But I think we will slowly see that he's not, and that there will be times where he won't even be privy to what's going on at certain points in the story because he just doesn't have as much control over everything as he thought he did. So if he dies, it'll be because of the kids he thought were beneath him.

I think it'd be nice if the kids were the ones to sort of break the cycle of abuse their parents laid out by not succumbing to the need to rule as Gods in a new world lol.
