The really goofy thing about Identity Crisis it never occurred to Jean Loring to, you know, just call Ray Palmer and say "I'm sorry I left you."
I mean, murdering your friends is a great plan
and all, but I think that was worth a try.
Oh, also the terrible plot hole where they expect you to believe a flamethrower isn't one of the world's most forensically identifiable weapons. It's weird, since it didn't matter at all who the villain was since, afaik, Meltzer completely invented Dr. Rape; why not Heat Wave? His power is he carries a flamethrower.
