As we saw in today's issue: Alec Holland is "Earth's Ultimate Savior" - Swamp Thing!
I thought that was pretty cool; I wasn't expecting it.
Does that mean Holland is the White Lantern?
A source that works for Warner Bros. said that the plan was for Deadman to become the White Lantern. It wasn't set in stone, so that obviously explains Swamp Thing. I was told that bit of Brightest Day info - and some info about the big bad guy in Green Lantern -- and it wasn't Krona! Again, this was right around when BD first started and wasn't anything concrete. I won't spoil the GL part of it, as it could potentially still happen.
Let's just hope I didn't spoil who the White Lantern is really going to be, eh?!
Guess, we'll find out in Brightest Day #24.
