Merlin is a BBC show that went on for 5 seasons it was a very popular show that got nominated for lots of awards. Which is now on Netflix(July 2020).
Summary
In this episode of Merlin there is a mysterious plague spreading all over Camelot. And during this time Merlin's friend Gwen's father get sick. So Merlin against his better judgement decides to help her father using magic. Which sets up Gwen to be the sorceress who has caused this trouble. So to clear her name Merlin finds out who really cause this to happen which turns out to be some kind of clay creature. And in the end there is a lady watching Merlin in a pool of water. Who I believe will be the villain in the plot later on.
My thought
Overall compared to how the 2nd episode this is much better.
