I've never saw El calling him father tho. He definitely calls El his son but El doesn't ca...

I think he called father but he is hesitating because he wondered if it just going to disappeare, like he thought that all of it will be gone, and he doesn't want to be fond but also want to.

I think one reason is tht the fakeass el was like the god was my father blah blah blah to el like tf this bish saying no one has a doodoo like u as a son
