Fast-forwarding approximately 75 years, Merlin (now an adult, played by Tom Sharp) returns to civilization after years of isolation in the wilderness—transformed by trials, faith, and visions. He appears disheveled and prophetic, proving his visions by predicting events (such as approaching enemies and water sources). He confronts Vortigern, negotiates the release of Christian monks, discusses the "Sword of Britain," and helps prepare the ground for a king to unite the lands against Saxon invaders (like Hengist). There is a focus on punishing the wicked, emerging alliances (including with Uther Pendragon), and a poignant reunion with his mother Charis at the end, in the place where she lived in seclusion. The episode highlights Merlin proving his influence amidst the chaos of war.
