Outlander Season 7 will introduce an adult version of William Ransom, Jamie Fraser's secret love child. While Jamie has told his wife Claire about William, very few people know the truth. In the books, it is revealed that Young Ian eventually meets William and realizes their familial connection. Outlander fans on Reddit have discussed Young Ian recognizing William as Jamie's son due to their striking resemblance. It remains to be seen if the show will follow the same trajectory, but William's role is set to become more significant in future seasons.
