 Guinevere later returns to Arthur from Lancelot's castle and is forgiven (Arthur starts to doubt that Guinevere ever betrayed him).When Arthur goes after Lancelot to France, he leaves her in the care of Mordred, who plans to marry the queen himself and take Arthur's throne.While in some versions of the legend (like the Alliterative "Morte Arthure", which removed French romantic additions) Guinevere assents to Mordred's proposal, in the tales of Lancelot she still hides in the Tower of London, where she withstands Mordred's siege, and later takes refuge in a nun convent (at Almesbury in Tennyson's more modern retelling).
