Joe’s always saying “We agree” in response to things.
But Joe’s not speaking on behalf of others.
Well, others that exist.
Joe’s not using the “Royal” we, per se.
Instead, he’s referring to the group that consists of himself and the voices in his head.
He thinks there’s an actual group, but there isn’t.
Who are the voices in his head?
Oddly enough, they consist of several kings of England.
They’re a rather murderous lot, and tell him to kill and behead the people who disagree with him.
I mean them. All of them.
(I hope he doesn’t murder me.)
