We really don't have a lot of interaction with Yugiri so I'm not terribly worried. Haurchefant was introduced sometime in the 2.X storyline and he had time to develop as a character where he stuck up for the Warrior of Light and had their backs through the thick and thin and even in the darkest hour. His sudden death trying to protect the WOL made the scene all the more tragic because of how well we got to know him and it made the WOL want to bring justice to Thordon and his Heavens Ward knights for killing him. That's why his death works so well and that's why I'd be livid if they brought him back in any form just to tease the heartstrings of the audience for the heck of it. His story is finished.
