Ep 4. Aithusa

Merlin season 4 episode 4, "Aithusa", begins with Morgana on the run, trying to evade her pursuers and stay hidden in the forest. She comes across a young druid boy who is trying to escape the same fate as she is and the two form an unlikely bond. Meanwhile, the knights of Camelot are searching for a dragon egg that the king believes could be a powerful weapon against their enemies. Merlin sets out to find the egg and ends up stumbling upon the boy and Morgana.

Merlin is shocked to see Morgana, as she was thought to be dead by everyone in Camelot, and her presence raises questions and concerns for Merlin. The two have a conflicting history as Morgana has previously been an ally and friend to Merlin before her betrayal. However, in this moment, Merlin puts aside his suspicions and agrees to help the boy and Morgana.

In the chaos, the boy is fatally wounded and Morgana realizes that she has some kind of magical power that she uses to heal him.

As the episode progresses, it becomes clear that the dragon egg they possess is not ordinary, but rather a harbinger of something much bigger. The egg hatches into a baby dragon named Aithusa and Morgana is instinctively drawn to it. Despite Merlin's warnings, Morgana sees the dragon as a symbol of power and decides to keep it for herself. Merlin tries to intervene, but Morgana uses her newfound magical ability to overpower him and escape with the dragon.

As the episode draws to a close, Merlin and the knights begin to understand the true nature of the dragon egg and its significance. They realize that Aithusa may not be just any dragon, but rather a creature that could change the course of history. Merlin vows to try and find the dragon and retrieve it, knowing that its power could be a threat to Camelot and all he holds dear.

Overall, Merlin season 4 episode 4 is a thrilling and action-packed episode that sees the return of a beloved character and the introduction of a new, powerful creature.
