Gerlois shows up and gets all jealous, then drops the bad-news bomb that The Authorities is Uther Pendragon his own personal self, the new High King. I wonder if this was the important thing Ambrose told the capos, and why Uther wouldn't stay in the room for the important stuff, especially when it was about him. Anyway, Migraine's eyes water, and she looks at her feet, and Gerlois is trying to set things on fire with his mind, but he can't because he's only a Christian, and Uther says something about not to envy him. Because he doesn't have Migraine. Because he's a big drunk. Because of his chronic body odor. Because neener-neener I'm going to screw your wife in a second, so bye. Because being boss is already giving him agita. He exits to be High King in some other, less domestic-violence-oriented location.
Gerlois freaks out on Migraine for Hanging With Mr. Uther, and she wisely decides to keep mum about the apparently mind-blowing sex she may have had with big old Uther in their other lives. Then Gerlois freaks out on Migraine, because women who spend time with Uther receive demerits in Gerlois's Big Book o' Judgments or whatever, and Migraine has a backbone attack and tells him he's a jerk for thinking she would fool around on the good thing she has with him. Because the good times are really, really good, and she's made her peace with being put under the occasional house arrest, or smacked around for having epilepsy. Gerlois reaches out because this is somehow obscurely an insult to his masculinity, and then Migraine's eyes don't water even a little as she tells him that if he is thinking about hitting her, he better shove that egg right back up the chicken because she will totally do some dark magics on him, or something equally bad, like forcing him to sleep with the Queen of Mean, or take Merlin with him next time he goes out drinking with the guys. Because Merlin hates being seen as just Vivarin's bitch, and always feels left out when they come over.
Later, a messenger comes from the new High King to ask for Gerlois' troops in the fight against the Saxons. Particularly glaring here is Gerlois' Angel-caliber awful accent, and he and the messenger from Uther get into a yelling pissing contest which is more than anything a kind of Bad Accent Bee. There's overacting and yelling and repetition, but the gist here is that Gerlois would rather keep his troops in Cornwall than send them to Camelot. Which makes total sense, except for how Gerlois lives in a feudal setting in which his wealth, title, prestige, trophy wife, and home all come from the central idea that his men are Uther's to do with what he thinks is best. Logic is not what Gerlois is all about, right now. He still hates Uther for talking to his wife one time in public, so much so that he is willing to go rogue and actually take his men to Uther's camp, sneak up in the night like a cowardly jerk, and kill Uther, the High King of all Britain, for not really any reason at all.
