Dramatic irony - Mat in Tear at the same time as Egwene and others
As the plot culminates in Tear, all the protagonists gather there, unaware of each other. Mat, in particular, who is searching for Egwene, Nynaeve and Elayne is situated in the town at the same time as the three of them are, not far from where they are. Mat discovers about their whereabouts too late, they’ve been already taken by the Black Ajah, and regretfully comments on the irony of it. The readers are aware of all of them being in Tear at the same time, while each of the characters are unaware, which makes this a dramatic irony.
Irony of Faile and Perrin
It is ironic how Perrin wants Faile gone the entire time she’s perched up on his side like a falcon, but once she’s in danger he risks his life to save her in the dream world. Min warned Perrin about the falcon that will start following him, and Perrin realizes at the end that Faile is that falcon.
Dramatic irony - Rand at the Stone of Tear
Rand isn’t much present in this novel, despite him being the main source of the plot. He goes on a hallucination-filled journey to retrieve Callandor, but he is unaware that all his friends follow behind. The reader is aware that all the protagonists are journeying towards Tear following Rand, while Rand isn’t, which makes this a dramatic irony.
Situational irony - Mat and Thom Merrilin reunite
In an unexpected turn of events, Mat, after escaping the gray men, reunited with Thom Merrilin, and the two decide to travel together. Thom has fallen into alcoholism and depression after the events from the previous novel, and the sudden appearance of Mat is his way out of that. The reunion of the two of them is sudden and unexpected and creates situational irony.
