There's an aspect of Original!Elias Bouchard that makes me so sad to think about in a weird kind of "meta" way.
And that's the fact that he has to be labelled as the "OG" not as Elias.
Technically speaking Elias has been dead for years. It's Jonah that's taken over - literally having his eyes removed and replacing them with his own and living as him (he even seemingly keeps his "old fashioned haircut" on Elias' hair).
And yet we as the audience don't often call that form of Jonah "JONAH". Instead it's Elias, cause he's been Elias for 4 series at this point.
"Elias started the apocalypse", "Elias beat that old man to death with a metal pipe" when it was never really Elias in the first place.
He's been so robbed of his own identity that not even death can spare him; all of Jonah's actions in his body are recognised as him.
(Btw this isn't me saying you can't call Jonah!Elias straight up Elias, I do that regularly ofc. I'm just being emo rn lol)
