Aqua doesn't know the situation. She doesn't know the world politics or anything other than exactly what she saw. But to someone who has stared down the heart of darkness itself...

She shakes her head. "I don't know either of you and I've never met him. But nothing I could see in that moment suggested it was like that. It takes a special kind of darkness to trick someone for a long time. Especially someone you love. I know what that looks like. It's smiles and lies and when it's all over... they're triumphant. This... your friend wasn't that."
