This was my theory back in S1:
Adam being the 'Bad Apple' for Eve might just means that he is a threat and a problem with regards to Eve's growth/research/experimentation results. I think that it didn't hindered but worsen Eve's capabilities after all his first emotion is envy and this past Eve was like a real kid that goes ballistic over little inconvenience or something that upsets him. Adam being guilty over what Eve's becoming, he later on tried to take his life. Resulting to what we currently know. And as for Isaiah and Gabriel's eye, it might be connected to Eve's first tantrum. They might have their current probably due to what Eve did on Adam's after losing his sight.
Yeah, that's all I can speculate for now. But damn, past Eve is a certified black flag. I'm just so glad that Eve rn is such a puppy.
I like this unhinged Eve but the current Eve is just too adorable. Now basing from this new chapter, my theory from season 1 was quite confirmed. As a result, Eve revived or saved Adam and for it to prevent from happening again or just removing the pain he's feeling which is foreign to him... he erased his memories.
It all goes back to Adam's insecurity and feelings for Eve and Eve's lack of emotions or him just focusing on his obsession with Adam which later on would slowly kill him.
ALSO THE FUCKING ARTSTYLE IS SO FREAKING PRETTY.
