I dig it. If III ever does another AMA, we should keep the “How does a GK come to be?” as one of them.
It could be a bigger problem they’re worried about…maybe III is being controlled somehow by someone else and that’s really who they’re scared of.
Also, more to theorize about….but what if after III’s birth, he smashed whatever birthed him, this making sure he was the final Gatekeeper. Maybe he didn’t want to share the spotlight and took it upon himself to make sure he is the final one.
