If you recall, Season 2 concludes with Rhaenyra and Alicent Hightower (Cooke) reaching a tenuous alliance.

However, little does she know that Larys (Needham) is sneaking the king into Braavos during this rendezvous. Meanwhile, we see Team Black and Team Green prepare for battle. Season 3 will open with the highly anticipated — and bloody — Battle of the Gullet.
