"He doesn't know." Not that it would matter. It wasn't like she was changing Aiden's name from Crowley or, god forbid, from Mcleod. She was changing it from Milton. Crowley hadn't deserved Aiden in the first place, this was just another step in the direction he'd pushed her to. It was his own fault and he knew it. He had no one to blame but himself.
"It doesn't matter. He doesn't matter." Not anymore, anyway. Especially because this is what Aiden wanted. She spoke to her son about it. Kind of. She spoke to him about Crowley at least. This is what was right. What they all needed.
