Morgause s Parents It was recently learned that she has a half sister Morgause who was smuggled out of Camelot by Gaius at her birth and it was revealed by Gaius that she is the daughter of Gorlois The identity of her mother remains unknown We can t know Gorlois is Morgause s father for sure just from the crest she wore and in fact it seems like its the other way around from recent events Helen I believe is her name Gorlois wife seems to be the shared parent of Morgana and Morgause Spoilers for 3x05 if you haven t seen If Morgana and Morgause share a father why did Morgana continue to call Morgause sister after revealing to Morgause that Uther was her father They would be entirely unrelated if Gorlois was not Morgana s father And you would think the subject would have come up Also the way Morgause mentioned that the healing bracelet she gave Morgana was a gift from her mother seems to imply more that they share a mother and not a father
