I don't know how or why i thought of this, its also probably a bad idea but I was thinking what if Lian Harper is the chosen one to wield the white lantern?  It would make fr an interesting story and all, especially since her father is a villain now.   I can picture the white lantern bringing someone back to life who was killed before their time, and someone who is "pure" at heart.  What do you think? Who do you think?

I have thought of this as well, and it could be possible. It would be cool, and I would love to see Lian back. I have also thought that it might end up being Deadman, after he embraces life, like he was instructed to by the white entity.
