Accolon follows her outside. Arthur, in the meantime, is taken to bed, barely awake, by a spirited Lancelot and Gwenhwyfar. Arthur then brings up how he notices Lancelot and Gwenhwyfar looking at each other, and how Gwenhwyfar has no child. Arthur, blaming the lack of an heir on himself, suggests that Gwenhwyfar sleep with both him and Lancelot in the hopes of conceiving the needed heir. Arthur emphasizes that Gwenhwyfar will be able to swear that the child was conceived in the king's bed. Lancelot and Gwenhwyfar are both skeptical, but Arthur persuades them, and they all bed down together. Meanwhile, Morgaine and Accolon kiss amongst the dancing pagans. The next day, Lancelot is feeling regret for what he has done with Gwenhwyfar and Arthur. Morgaine realizes that Lancelot will never love her, so she devises an alternative to Lancelot feeling regret and sadness all his life. Gwenhwyfar has, by this time, gotten her period, and therefore still remains barren. Her serving woman, Elaine, is ecstatic, as Lancelot (encouraged by Morgaine) has asked her to marry him (she was previously seen looking at him). Gwenhwyfar, angered and distressed, dismisses her. Gwenhwyfar is also annoyed at Morgaine, who promised the charm would work, and resents Arthur for insisting the threesome would work. At Lancelot and Elaine's wedding, Morgaine speaks with Merlin. Viviane is absent from her son's wedding, as the pagan banners of Pendragon have been taken down from Camelot due to Gwenhwyfar being hysterically upset with the "painted savages." Meanwhile, King Uriens discusses taking a second wife (he is a widower) with Arthur, and out of spite, Gwenhwyfar suggests Morgaine. Arthur is not too keen on the idea, but he and Gwenhwyfar ask Morgaine. Gwenhwyfar carefully words the proposal, and Morgaine thinks it is Accolon proposing, and accepts. She only finds out too late that she was engaged to the father, and not the son. Morgaine decides that it would be for the best to go through with the marriage, as Wales was an important political ally. Merlin, upset by Morgaine leaving Camelot with Uriens, leaves the feast. Merlin, upon returning to Avalon, dies of old age and tiredness, with Viviane horribly upset, and Avalon filling with mist.
