I’m not exactly an Alex defender and I get you’re trying to be fair, but this is where I say it’s not “little reasons” it’s clearly trauma, just like Ava was going through trauma and Meredith’s childhood trauma, he had an abusive alcoholic father and then obviously took care of his unstable mother and Ava was a trigger… so yea he was a prick but it wasn’t just Alex being a prick because of reasons he wasn’t acting sanely.
