A studio audience applauded as they watch the talk show of host David Arts waved to all of them before sitting down into his chair.

"Well folks, tonight we have a very great show for you tonight," he said. "Let's kick things off by welcoming our special guest. She is the best-selling author of the "Cooking with love" book and is a world-renowned chef known around almost the entire world. Please welcome Miss. Greta Bacin."

At that moment, Miss. Bacin came out from behind the curtain but instead of smiling and waving to the audience, like most gusts would do, she ran out screaming with a look of sheer terror on her face.

"Everything all right?" David asked, a bit concerned for his guest.

Miss. Bacin started pointing at the curtain she came out of and could only let out a few stammering words before collapsing onto the ground.

David ran up to the unconscious woman and checked to make sure she was ok.

"She's fainted," he told his audience. "Somebody call an ambulance."

Most people took out their cell phones and dialled 9-1-1, while others just watched, believing that the whole thing was just part of the show.

David soon got curious at what she was pointing at. He went up to the curtain, torn it open, and froze dead in his tracks at what he saw. Lying on the ground backstage was the body of a man wearing a white dress shirt and blue tie. The man's throat had been slashed opened and right beside the body was a broken coffee mug covered in blood. Next to the mug was a folded piece of paper. David picked it up and unfolded it. Written in red ink, the note said:

"SO LONG AS YOU WON'T MISS IT."

David then took a closer look at the body and saw two big cuts on the sides of the lips, making it look like a ghastly smile.

Quantico, Virginia.

Dr. Spencer Reid was sitting at his desk, reading a book. He then placed his hand inside a small bag on his desk, pulled out a piece of candy corn, and popped it into his mouth. But as soon as he bit into it, a sharp pain surged through his mouth, causing him clench onto his jaw and let out a painful groan. Derek Morgan and David Rossi were walking by when they saw Reid rubbing his cheek.

"What's wrong kid? Bite your tongue," asked Morgan.

"No, it's this tooth," said Reid. "It's been hurting for almost a week. I thought it would go away, but it's just getting worse."

"Here's a crazy idea," said Rossi with a bit of sarcasm in his voice. "Go to the dentist."

"No! No-no-no-no-no-no-no-no-no!" Reid said repeatedly. "I am not going anywhere near a dental office. You can't make me."

Morgan and Rossi were a bit amused at Reid's nervous act.

"Don't tell me your scared of the dentist, Reid?" asked Morgan.

"The proper name for it is Dentophobia and yes I am," said Reid. "I don't like the idea of some strange person sticking their hands into my mouth and poking at my teeth with sharp objects. It sounds like a form of medieval torture."

At that moment, Aaron Hotchner walked up to the three agents.

"Everyone to the conference room. We got a new case," he told them. He then eyed Reid rubbing his sore jaw. "You should see a dentist."

"Don't bother Hotch," said Morgan. "Our little boy genius here is a scardey cat when it comes to dentists."

"Actually, it's a well known fact that 75% of people in the United States alone are considered to have dental fear," said Reid, going through one of his trademark rants. "A study has estimated that 9% of those people are children."

"Well then I guess Jack is not one of those 9," said Hotch, refereeing to his son. "He loves the dentist."

"Really?" asked Rossi.

"Yes," said Hotch with a smile. "Well, actually he loves the dinosaur stickers he gets after his check up a bit more."

The team then headed into the conference room, where JJ, who was already sitting at her seat at the table, greeted them. Kate was not there as she was still at home dealing with her pregnancy. As the team members all took their seats, Penelope Garcia entered the room and gave each of them a folder.

"Greetings my fellow crime fighters," she said. "Today, you will be heading to Los Angeles to help with a really bizarre string of murders."

Garcia then pointed a remote to the big screen TV in the room and click a button. The screen then revealed a picture of an elderly man with a baldhead and goatee.

"This is Thomas Thurston, age 57, works as a child psychiatrist," said Garcia. "He was found dead backstage at a studio during a filming of the David Art show last night. His throat had been slashed opened with a broken mug which was found next to the body as well as a note."

A photo appeared onscreen of Thomas' corpse lying on the ground of the set as well as one of a close up of his slashed throat, one of the bloody mug, and one of the note.

"Yeah, I watched that last night," said Rossi. "His guest came out screaming and fainted in front of the audience. They had to cut to commercial."

Garcia then clicked at the screen again. This time, a picture of a middle aged woman with red hair appeared onscreen. Next to it was a photo of the same woman lying dead on the floor. The next photo was of a close up of the woman's forehead, which had a gunshot wound in the middle of it.

"Two days before this, Karen Oliver, a 46-year-old ad executive was found lying dead from a gunshot wound to the head inside the maternity wing at the local hospital."

"Those poor babies," said JJ.

"And are these deaths connected somehow?" asked Hotch.

"Actually yes they are," said Garcia. "Both victims were found with large cuts on both sides of their lips."

Garcia clicked at the screen again to show two photos. Both were of the victims' faces, which showed the cuts, making them look like they were smiling.

"Talk about going out with a smile," said Morgan.

"The LAPD wants us to help catch whoever is doing this before someone else is killed," said Hotch. "Wheels up in 30."

As the teammates left the room, Reid stayed a little bit longer to look over the victims' photos again.

There was something familiar about them.
