He did. It was discussed somewhere in the threads before Lori’s trial. He had custody for awhile while a mediator was working with with both parties. Iirc, Melanie was pregnant with Ian’s child and they now have two. As I remember, Ian played a part in getting her out of the cult but she seems to still have a chip on her shoulder and I have never seen or heard of her apologizing to Brandon. I believe she knew Alex would murder him, or try, but she denies all culpability.
And even though Brandon still breaks down on the stand she is icy cold like she owns the world.
A lot of people give her a pass because of her childhood.
I know very very few people, myself included, who had “good” childhoods. But we make it and we put the past behind us. We grow up and do the decent thing.
Melanie? Not so much!
