User blog comment:Fimber/Why I understand Uther's reasons for banning magic - and why no one is a saint on "Merlin"/@comment-24.26.233.208-20120707142059/@comment-5102537-20120707143640

We don't know if Uther had cheated on her. Since Morgana is older than Arthur it's entirerly possible and likely that he had his short affair with Vivienne before he was with Igraine. Although it's also possible that he had already been together with Igraine at that point of time, I don't believe so, given that Uther hadn't been together with any woman after Igraine's death. When is was so faithful that he he hadn't even kissed another woman after the death of his wife I don't believe that he would have cheated on her while she was still alive and they both obviously deep in love. Why else would he call Igraine his heart and soul if it wasn't deep love?
