Today in my Judaism class my professor was explaining how in the Midrash (and now you're wondering what the hell this has to do with FMA, but I'm getting to that), after Ishmael and Hagar are forced to leave the house and Sarah dies, Abraham actually marries again to a woman named Keturah, who is, purportedly, Hagar, who waited around all those years in chastity for Abraham. It also states that upon Abraham's death Isaac and Ishmael buried him together, implying that they had a reconciliation upon their father's death.
Okay, now the FMA associations. I, unfortunately, am not up-to-date on the status of Edward's extended (and admittedly weird) family through Hohenheim (and by extended I mean Envy), either in the manga or the anime. So, I'm asking those of you who do know:
Do you think the situation between Hohenheim/Trisha/Dante (or minus Dante in the manga) could correspond to the story of Abraham, Sarah, and Hagar, with Ed and Envy represented by Isaac and Ishmael? Or am I just reading too much into things again?
