Much of North America is unpopulated in real life, too.

Jersey is the name of an island in the English Channel, but it is not part of England and its name is not from the English language; "Jersey" isn't an English place name.

("Jersey" isn't an English place name.)

He definitely documented the pyramid in his journal.

Perhaps I shouldn't have said "just as much"; to my surprise I can't find any actual research addressing the variation of singular they according to education. However, the papers that I can find (Baranowski 2002, Laitinen 2007) do find that singular they is used the majority of the time, more than generic he, in all…

That's not true; educated people use singular they just about as as much as anyone else.

Empire City.

Whee, I added that link to TVTropes because it was discussed in this comment thread. :)

…Whoa.

Yeah, but it's a conjecture that Blue Diamond only came to earth after Pink Diamond had been shattered, so "the timeline" isn't definitive in this respect.

Eyeball stated she was an eyewitness to the event.

Homeworld must have retained some presence on Earth after Pink Diamond's death long enough to build the pyramid temple from Serious Steven, though—that had the three-diamond logo and a mural of events of the war. They can't have abandoned Earth immediately after Pink Diamond was shattered.

Yeah, I don't understand how/why anyone jumped to the conclusion that Rose used a sword to shatter Pink Diamond. If the episode had said that she did, that would be an interesting discrepancy suitable for theorizing around. But since the "idea that Rose Quartz shattered Pink Diamond with a sword" is *itself* unfounded…

I mean like… I feel like you're overthinking this? Here's what I see happening:

I think there's a third, and much more likely, possibility: Rose *had* her huge sword, the same one we're all familiar with, but shattered Pink Diamond by some other means. (Also, a fourth possibility: Rose didn't have her familiar huge sword while shattering Pink Diamond, but Eyeball saw Rose's sword on some other…

New hypothesis: type of weapon depends on position of the gem on the body maybe?

(except Yellow Diamond)

Lion's mane seems to contradict that hypothesis.

A recurring thread through season 1 seemed to be Steven's role in bringing gems and humans together as part of the same community—I theorized back then that that was Rose's reason for making/becoming him, or one of her reasons. I'm kind of sad that that thread's been on the back burner for a while—the Beach…

We don't really "know" that; but it is a reasonable possibility given the information we do have.
