Vivarin wonders if they've wasted their lives, and Merlin replies with some stuff that makes no sense, and he's talking slower and slower about "live with passion" this and "find a little joy in life" that, and delivers some kind of WTF statement about how the Goddess lives in our humanity. Vivarin begins weeping copiously, and we figure out Merlin is dead. How can she tell? Then she sobs really loudly for a long time, because having your only living fan die in front of you is hard on ye olde ego. Then Raven, the main bald womyn of the island, gets behind Vivarin and kneels and tries really hard to cry but gets distracted by some Mists that are filling up the abbey. She walks around all tripped out because there is heavy-duty Mist all over the place. Raven is upset because she hates Jamie Lee Curtis movies and this is just like the one called The Fog. There's more Mist and more Raven and more sobbing. I think it's supposed to be portentous, but I don't get it. It's fog. The thing is called The Mists Of Avalon, for Pete's sake.
Margulaine tells us that she was only ever happy in North Wales with her ancient husband, and that when Sir Accolon came to visit, it was just like a family. I understand that, with all her experiences, she might be confused about what families are actually like, but I think any family where the woman was tricked into marrying the husband because she had a hard-on for the son is decidedly non-standard. There's a sexually charged scene involving Margulaine, her son, and a bird of prey. Happy little family. Meanwhile, Mordred is growing up to be creepy as all get out, into "a manhood that would destroy [them] all." Vivarin appears to Mordred, tells him he has to be the Harvest Home Womyn's Collective's main champ, and then without prelude informs him of his status as Incest Bastard. He takes this news rather well, apparently having figured out that Vivarin set up the whole thing. He makes some really embarrassing summer-stock faces, and I can't even really look at him as he froths, "Yes. I have the power...I can bend men to my will!" There is more related Dr. Doom speechifying before he agrees to fight for Vivarin.
The next scene happens really fast. Incest Bastard runs into the Orkney dungeon where the Queen of Mean is hanging out and yells at her for not telling him about the whole incest deal, and then the Queen of Mean tells him to go to Camelot and discredit Arthur through his wife -- like that would be hard -- and then there's another embarrassing frothing monologue about how he wishes he could see his mother and father as just people instead of mythical superfreaks and how gods and goddesses mess up everything, and then he decides to kill Arthur, and then he laughs weirdly, and then he starts drinking even though it's only 10:30 in the morning.
