...Helen could be. It's hard to say. Her mother, Nemesis, can jump between dimensions. She doesn't have the highest regard for humans, so she might have grabbed her and ran. But I doubt Helen just died. Even when her body is completely destroyed, killed by some magic thing, she reincarnates into a new life. She's always alive. Don't know about her exes though.

We have a thing in the Luminaries; So insane or lame, we go around and kick butt.

So, the smiley is just par to the course.
