The season 3 finale of The Wheel of Timehad an incredible twist surrounding Mat Cauthon, fulfilling a terrific moment from the books I was worried wouldn't make it in the TV series. The Wheel of Time season 3's ending saw Mat travel through a redstone gateway, causing him to come face to face with an Eelfinn, a extradimensional being capable of granting wishes. This might have been a bizarre scene for TV fans, but it's drawn from material in The Shadow Rising, and it introduces an unforgettable side of Robert Jordan's world-building.
