So this is quite simple. Arthur Tudor marries Katherine of Aragon, but he dies half a year into their marriage. He leaves her pregnant, meaning the marriage is DEFINITELY consummated and she can't claim she was a virgin later on to marry Henry. However all this is moot, as she would die in childbirth giving birth to a healthy son at a young age.
What butterflies will result from this? Henry will not be king, but who will he and this new infant king marry?
