I don't care what you say, Brad; I know who really killed Sue Dibny.
We all know it wasn't really Jean Loring, because, well, that doesn't make any sense. Duh.
I always suspected it was beloved DC nutcase J'onn J'onzz. I mean, "Identity Crisis" should be the title of guy's biography. "Today I'm a cop! Now I'm a cat! I mean, Bloodwynd! Next year, I'll have amnesia! Again!"
Now I have the missing piece of the puzzle: motive.
Not a jury in the world would convict him.
The real shocker here is not that The Martian Manhunter and Aquaman used their telepathic and other abilities to get away with murdering Sue for painting their apartment chartreuse 20 years earlier.
It's that they live together and both know the word "chartreuse". Lordy, I personally am gayer than Liberace swimming in a pool of "Eternity", and even I barely know what chartreuse looks like.
Amazing men, those two.
