Honestly, This Has To Be Confirmation That Proto And Earth Are Indeed Separate Characters. For Those

Honestly, this has to be confirmation that Proto and Earth are indeed separate characters. For those not in the know, it's been a long running debate in parts of the fandom about whether or not Proto and Earth are the same or their own different characters.

But this new episode not only has both of them show up, but Theia outright tells our Earth that his "essence" (which I believe means his core) belonged to the both of them and the last line of the episode is literally, "This is the story of your creation," to Earth.
