I wonder who was the man with whom Angel was once in a relationship.
As Angel told MC about him, she said he was divorced, had a son (whom he didn't mention much), and had a woman who couldn't give him children. And he was an asshole. It kind of suits father MC. (divorce, the son about whom I am told nothing) The only thing I don't know is whether Elaine can have children or not.
I don't know, I'm probably wrong. But knowing Father MC how he cheats on women, I wouldn't be surprised if it was him.
