What's red and black and sexy? Charlie; recently back from Oz our favorite little hacker is out for revenge. This isn't the little Charlie we last saw, nor is it the adorable nerd we love. She's on a war path. But for whom? In previous seasons we learned that the girl we know has a dark past. When she was a kid, Charlie got scared at a sleep over and called her parents to pick her up. A drunk driver hit them and from then on her life was never the same. It seems that Oz has done enough damage to make Charlie seek out all those involved with the case. She hits up a few people, not killing, but torturing, until she gets a name of a councilwoman.
Sam and Dean are in disbelief that this is the girl they know and love. Charlie takes the woman's bank statements and then promptly kicks Dean's ass from here to Sunday. War from Oz has made Charlie pretty awesome. She takes off after popping the tires on Baby. Just as she leaves Dean in the driveway swearing, another car pulls up. Thinking its Sam, Dean is shocked to discover Charlie? There's two of them??!! That's right, there's two of them. A light and dark side. Good Charlie explains that the wizard had to split them in two in order to win the war over emerald city. After that, dark Charlie escaped to hunt down the person responsible for killing her parents. Once back, however, she breaks the key, stranding them both here. Battling the darkness has never been more literal.
Sam and Charlie take off to find any clues as to how to fix the key. Dean stays behind to protect the man that ruined her life. Only to face dark side again. She plays it nice and gets alone time with the man who made a terrible mistake all those years ago. She stabs him with with a sharpie before fleeing. Sadly, there is no cure for a permanent marker stab wounds. I never even thought Charlie could hurt a fly.
Meanwhile, good Charlie and Sam find a retired Men of Letters member. He had been to Oz several times. He tries to play the two off like they're wrong, but he drops the act to help. While in Oz, he was forced to be split into light and dark. The dark version of him became The Wizard. Bad news, there is no fixing the key. By the time Dean gets to where Sam and Charlie are, dark Charlie has a plan...the two fight it out, but any damage done to Bad Charlie hurts the good half.
All while our Former Men of Letters does something drastic, shooting himself in the stomach brings the Wizard here. Charlie shoots the good version of the Wiz in the face before the Wizard can kill Sam. Soon beaten by Dean, who nearly loses it and kills Dark Charlie, the two are finally reunited, and made whole again. With no key to Oz and a broken arm, Charlie decides to stick around and help find a way to remove the Mark. Dean is beating himself up even more so than usual, but alls well that ends well. At least for this episode...
