I don't think it's her brother. Think abt it she said that he's with that mercenary grp that her father used to lead which the emperoor don't know about and he(emperor) still haven't found her brother coz he doesn't know the whereabouts of her brother.
Sry this msg was for the other comment.
Even though aideen killed his brother i wonder if he was brainwashed by the king bc it doesn't quite make sense hw someone like him would be on their side, i bet he was brainwashed
I think so, too. It seems like their whole agreement about her betrayal so he can conquer the Emperor's country is built on a house of cards. All it takes is the Emperor brainwashing him, somehow, and it's back to the guillotine for her.
Also, letting him know about the brainwashing gives him a chance to ... I dunno, not be brainwashed, right?
