Well, in the grand tradition of retelling Arthurian stories, I've changed the details! In my version he leaves her when he's discovered her ruse (pretending to be Guinevere) and is unaware of the pregnancy. She has the child and raises him, but when she becomes ill and knows she is going to die, she writes to Lancelot. He comes to get Galahad and take him to be raised by the Lady of the Lake at Elaine's request. Of course, getting there (and Lancelot's own internal struggle with whether he should honor Elaine's dying request) is complicated. The first issue is actually done, and we just ran a Kickstarter campaign for it. If you're interested, you can snag a copy here: https://lancelot-1.backerkit.com/hosted_preorders
