Tommen, in A Feast for Crows, becomes ill in the Sept due to the overwhelming smell coming from his grandfather's corpse. Cersei makes him stay down there for hours with the family as they formally grieve, but he is made ill by it all. Cersie is furious when he vomits (adding to the smell in there), but Jaime urges her to be forgiving and to stop being so harsh toward the boy.
