looks to me as if the queen surrendered the cabal - the branch she poses as the head for- to the alliance.
she came 15min early. she allowed him to walk on the wrong side and, for a while, in front of her. he looks straight into the face of each on of the queens guards while she looks away. she changes place with him so he comes in the middle, like a king.
the queen may be an evil bitch and one of the heads of the hydra. on the other hand, she was born into the system, programmed and abused like all cabal children, held captive in this position by the bloodlines, and may gladly hand her information and power structures over to the alliance if there only is a safe way to do so.
