The emotional core of the finale was Kyle McLusky's pursuit of Merle Callahan. After Callahan murdered Kyle’s wife, Tracy, Kyle’s spiral into despair turned into a singular mission for vengeance.

There, Kyle finally got his justice, but it was as ugly as fans expected, cementing the idea that in Kingstown, 'hell is home.'
