Okay so I’m assuming that Adam and Isaiah were in a happy relationship, Eve (then Michael) wanted Adam and manipulated his memories of his relationship with Isaiah so they would breakup. Now Adam is free to be Michael’s (guide).
Adam used the artificial enhancer to guide Michael but eventually the side effects ruined his eye.
Isaiah is still probably in love with Adam since their relationship ended artificially and when Adam lost an eye he gave him his own.
Michael felt so guilty about how he was the cause of Adam’s pain and manipulated Adam’s memories again to make him forget and the destroyed his own memories of Adam so he wouldn’t seek him out and hurt him again.
