This weeks' "Criminal Minds" Season 10 Episode 6 goes this side of fantastical with a twist of Grimm's more horrifying fairytales. And it starts, ironically, in the Jareau-LaMontagne household, where JJ struggles to explain to her son how she had lost her sister through suicide.

At the BAU, the team is called for a new case involves what appears to be a rage-kill, where a man has been found stabbed multiple times, his car window smashed and his cellphone stuck inside is mouth with its alarm ringing for midnight. And as the BAU team head out, a new victim has just been added to the body count.

The new victim has turned up before the police can even leave the dumpsite of the first victim. Between theories of gay hate-crimes and revenge against deviant sexual acts, who knew that a woman would be behind the murders? As it turns out, the odd mark on both of the victims was just one of the single common points. JJ (AJ Cook) pointed out that the mark looked similar to the latest pair of Jimmy Choo that she had just seen in a catalogue. Apparently, it was only a matter of time until a pair of stilettos became a murder weapon for the long-running "Criminal Minds."

Meanwhile, the blond woman who first appeared to be the next victim is now proving to be the potential unsub. She's shown tying a man that she has just met to the bed, while the man expects something great to happen in the next couple of seconds--instead he gets a stab wound to his torso.

When the last victim showed up with ashes on himself, things suddenly seemed to fit: it's a classic, albeit twisted take on the Cinderella. You have a young woman who meets a dashing man with a great ride. The only catch is that instead of the glass slipper being a key to happiness, it was the key to killing the Prince Charming who didn't live up to her fantasy.

Unsub Cinderella finds another ball to attend where she finds another beau she thinks is the one. A look could easily tell that the man is looking for nothing more than a fling, but as they dance, the haunting melody bodes a fantasy that will not end well.

The fairytale doesn't turn out its happy ending as Prince Charming turns this side of reality and expects more than what she was willing to give. The end result is her stomping on him with her heels and her leaving behind her bloodied glass slipper as she disappears into the night.

As the "Criminal Minds" BAU team try to find the unsub's whereabouts, Cinderella was visits what is supposedly visiting the grave of her father. And with her is a co-worker, someone who was actually good enough to be a Prince Charming himself, given his obvious feelings towards her. Things turn ugly when the beau realizes that the grave is marked for a woman who died in 1923--and the unsub Cinderella's temper and denial gets the better of her enough to bang him on the head. It's revealed that her perfect father was actual a pedophile.

But before she could go for the kill, Spencer Reid (Matthew Gray Gubler) plays into her fantasy as the Prince Charming and whisking her away into the waiting interiors of the police car. It's one that will never turn into the magical ride she ever hoped for.

With JJ now a little more aware of how fairytales can work for her kid, he tells her a brand new story. This time, it's a story about two sisters, who would look up at the stars even if they were not together, knowing that they would always be looking up at the same thing.
