I'm just gonna say what's been on my mind, Double is the main-villain and is a horrible monster who should be burned at the stake(But that wouldn't work, she'll strike again). And no I haven't watched Eliza's story(She doesn't interest me) but I am aware of what Eliza might've did to Aeon and Venus but that doesn't excuse Double of what it's done. It'll be like having some nutjob breaking into you home, smash all you're property, burned all your money and murdered your family. But it's okay because someone kicked her puppy so she's perfectly justified. And you should respond with shooting her in the face.
Sorry for the mini ramble, Double is a good villain but I find nothing redeemable about that thing..
