Listen, I get everyone is surprised by the fact that the emperor can't fight, but like, didn't we ALL see the cover? The EMPRESS is carrying the EMPEROR not the other way around. The baddy and her soft-boi male wife who only wants her to be safe. Call him what you want, but it was already heavily implied by the lack of action he takes and the ease of which is emotions are swayed and manipulated for the sake of other people.
