After having spent most of the game opening up to you and regaining his anima, when Llyud performs a Heroic Sacrifice, and takes an attack from Feolthanos meant for Vaan, although he survives, Llyud is striped of the anima he spent the whole game regaining. He's just an emotionless shell again. What makes this worse however, is if you go an talk to Llyud on the Bridge, or in the Sky Saloon, with him only saying that it "feels like a fire inside [of him] has gone", "words elude me", and the worst one of the lot: "..." Not only is it a Tear Jerker, it's a pretty darn big Player Punch too.
Earlier, there's the night where the party learns the truth about Velis, the man that they've been guarding since they became stranded, and who has been warming up to Penelo ever since they met. He is already dead. Not only that, but he used to be the Judge of Wings' lover, and she personally turns him into Odin and makes him fight you. Just before the battle, Penelo breaks down, unable to bring herself to fight him, and at the end of the battle, the party can't bring themselves to put him out of his misery. So Llyud, who has realized at this point that he is devoid of emotion, does it himself. Even worse, after that, Penelo breaks down crying, and Llyud says "I cannot even understand why you cry".
