i'm confused why did adam lose his memories

From the looks of it, sounds like Eve manipulated them or erased them.

I don’t mean that in a bad way, but moreso because Eve does not want Adam in pain no matter what. So it’s possible he did it for this reason… or maybe it was Isaiah being a dick that caused it too lol we just gotta wait to find out ╮(￣▽￣)╭
