1x04 The Dragon Reborn

This episode is much better than the previous ones, it seems the best one so far, with a lot of events and tension and fewer boring moments. The most interesting parts seem to be the ones connected with the false Dragon (played by Profesor from Casa de Papel) and his backstory, he is a rather convincing and intriguing character, not a one-dimensional evil madman but someone with a complicated story, he is capable of winning supporters by showing them kindness and believes that he can change the world for the better. In the episode, we have a closer look into the world of the magic of Aes Sedai and their relationships with their warders, Aes Sedai of different "houses" are shown so there is a lot of world-building in this one. Also, the affection between Lan and Nynaeve develops and grows, and they become more and more attached to each other, seeking their company (though maybe none of them would confess to what they really feel). There is a battle in which we can witness more Aes Sedai magic in action, and the special effects look quite good, as well as these used by the false Dragon. The biggest reveal in this episode is that Nynaeve is a channeller and a pretty powerful one, as she heals all injured people and manages to stop the dragon, as well as that she loves Lan as she uses the power she hasn't been even aware of in order to save him.

So much happens in the plot of Moraine, Lan and Nynaeve that the stories of Egwene & Perrin and Rand, Mat and Thom pale a bit in comparison, though these are also improved in contrast to what was on the show before. Unfortunately, Perrin keeps the boring pained expression almost all the time (he smiles only once) which makes him rather a flat protagonist and the least interesting of the three boys. There is also some worldbuilding in Perrin and Egwene's story as they get introduced into the beliefs of the Way of the Leaf and its total objection to violence, even in self-defence. The leader of the Tinkers tells Perrin the story of her daughter, which makes her a more relatable character. Analogous thing happens with Rand when Thom tells him the story of his nephew Owyn, who was gentled by the Aes Sedai, mistakenly thinking that Mat's behaviour which is due to the cursed dagger is caused by the fact that Mat can channel. This may lead to complications as Thom warns the boys to avoid the Aes Sedai so that Mat would not suffer the same fate, but if they do so, they would not be reunited with their friends. Thom is much more convincing character now that he does not sing. In the end of this storyline, it seems that Thom is killed as he tries to fight a fade on his own, telling the boys to escape, though from what I recall in the books, he survives. It may be different in the show though.
