It seems like you may have been the golden child, and perhaps Jem could have been the scapegoat? I don’t know how your mother interacted with him, but it’s been said you were the favorite. It may fit the bill, but it kinda sorta doesn’t matter anymore. It was what it was. There’s no excuse for what/how Jem is. I’m sorry Fiona. This is all very hard.

When you’re going through hell, keep going!
