Theories about OG Elias having any kind of agency over Jonah’s actions are so dumb to me, especially considering how often he emphasises that he does things because he wishes to. If he had another consciousness in his body battling for control, it would be relevant to his character. It wouldn’t be a tee-hee offscreen thing.
And it genuinely pisses me off when it’s not merely an urge that he ignores but something that actually slips out. You can tell that he puts a huge amount of thought into the words he chooses and he savours them as he articulates them. OG Elias-isms wouldn’t just “slip out”.
