King Jezal is in his chambers, when Bayaz strolls in with his usual complete lack of deference. Jezal chocks back his annoyance but when he turns and sees Bayaz in his travelling clothes his heart lifts. Bayaz is indeed leaving Adua, but he has one final directive before he leaves; the King is to obey Arch Lector Glokta in all things. King Jezal recoils at Bayaz’ impertinence, but the Magus crushes him to the ground with his Art. As Jezal writhes in agony, Bayaz hits him with some home truths: he is no descendant of Kings, but the son of a whore; and that deep down he is a coward. Blubbering, Jezal’s defiance crumbles into fear and timidity, and he agrees to abide by Bayaz' orders.1
Jezal gets one more little scene, but this is his last POV. For all Jezal's shallowness, you have to feel a little bad for his unfortunate ending. His character arc had by far the most emotional development and yet he winds up resigned to being a puppet King at best. He has discovered some admirable qualities like caring for others, but winds up trapped in a position where he can’t make any decisions of his own. He learns to love a woman, and winds up trapped in a loveless marriage, knowing that Glokta has married the only woman he ever loved. Personally, I think Jezal's ending feels right, but the periods where we think he could actually be a better person were too short, so his fall doesn't have the impact it should.
This is Bayaz' last scene too, at least until The Heroes. Well the evil old liar won didn’t he. And boy doesn't he go out with a bang with this exquisite trampling of Jezal's dreams. Maybe we don’t want him to win, but, hey, that’s the point. Well done Mr Abercrombie, you are a true master.
