Yes, really. ( ._.)

Like I kept saying, it's a resolved plot point. Deliora is from Gray and Lyon's childhood, and was the driving force for most of their lives up until Galuna Island when they finally got their resolution. Deliora's story, and to a lesser extext Ur's, should have ended there. It's already been dug up with Ultear, and now it's been brought back for the sake of, "Oh hey, this is Gray's dad. Now... DRAMA!"
