^ Yeah, the "third sibling" idea is always possible. S/he would probably be immortal, too. "Niece" does literally mean "the daughter of one's sibling," so unless they're still applying it to a more distant relationship affectionately or for lack of a better word....well, we'll just have to wait and see what the explanation is.
