10 years ago a 17 year old girl named Abbey Taylor allegedly took a gun to school and shot 3 classmates and a teacher before turning the gun on herself. A witness named Andrew Gates claimed that Abbey wasn't the shooter that someone else had killed those people and then killed Abbey. Andrew claimed that Jordan Matthew committed the Xavier Killings. His claims were dismissed because Jordan Matthew killed herself a year to the date. But he was insistent so the Police checked the security videos but they were missing and they have never been found. Abbey's parents and her younger sister who was 7 at the time moved away and changed their names.

Now it's 2012 , the BAU team is called to Boise, Idaho after a 17 year old boy named Trevor Wright was found shot to death on Spencer High School's field. In his mouth they found a picture of the first victim of the Xavier killings. His name was Jason Stayward; he was the football captain just like Trevor was. They believe this is a copycat so they canvas the school trying to find anyone who fits Abbey's profile. They come up with nothing. That night a second victim is found. The math teacher at Spencer named Mr. Victor Doyle was found in his classroom shot to death and in his moth they found a picture of the second victim who was also a math teacher. His name was Mr. Johnson.

Garcia informs them that Abbey's family changed their whole names. Her younger sister Amy Taylor now goes by Colby Hammond and she just so happens to be a senior at Spencer High School. They pull her in for questioning about the 2 kills and her sisters killings. She claims that she has nothing to do with the killings and she believes her sister is innocent. While she is being held a 3rd victim is found. 16 year old Michelle Tatroe an honor student was found in her car shot to death and in her mouth was the picture of Xavier's 3rd victim Natalie Otaga who'd been planning on going to Yale after graduation. The team believes she as an accomplice but she tells them she can help them with the case by telling them who the next victim is.

"The last student was Bradley Cooper. He was the school's bad guy. He was always in trouble. That's Kyle Brayson he is a total prick to girls, barely goes to class, and is always fighting," Colby says.

They get to Kyle just as the shooter shots him 3 times. Derek catches the Unsub in the arm but they still got away. The team gets Kyle to the hospital and he survives but they don't release the information to the public. So now they believe that Colby and telling her the truth. Garcia finally with Colby's help find the link between all the original Xavier victims. They had believed it was random because none of them fit into a certain category. Each one had some sort of dealings with Jordan Matthew. Jason Stayward was Jordan's boyfriend but Jordan found that he cheated on her. Mr. Johnson was having an affair with Jordan's mother causing her parents to get a divorce. Natalie Otaga was sleeping with Jason. Bradley had gotten her hooked on pain killers but stopped her supply after she refused to sleep with him. And Abbey was Jordan's best friend who started to hang out with Jason after Jordan's suicide. They pull up Jordan's file and find that she overdosed on her mom's medicine and that she'd been cremated afterward. They track down the witness to the Xavier killings Andrew Gates. Emily thinks the Unsub will kill their self as the final victim like Abbey did since it will be 10 years to the day so that gives them 6 hours. Andrew is flown out to Idaho and he recaps his eye witness account.

He claims that all 4 victims were in the hallway by the office during lunch period. And Jordan showed up dragging Abbey by her hair. Jordan began yell at them and shot each one like a million times. Then she turned the gun to Abbey and said

"I thought you were my best friend," the she grabbed her hand making her hold the gun to her head and killed her.

When they asked him how he saw all this he said

"I was caught skipping school so I had a lunch detention," With time running out they get a statement from Kyle Brayson who says Doris Cook Spencer's Principal shot him. Garcia does a back ground check on her and find that Doris Cook has no records until she was 18 years old. Andrew sees the picture of Doris and tells them that she is Jordan. He said that she changed her appearance but she still has the scar she got when she fought Natalie Otaga before she died.

"So if the Unsub is Jordan and she's repeating the killings all over again she's not going to kill herself. She still has one more victim," Rossi explains.

"All the other Spencer victims have matched the Xavier victims. So she needs a quiet loner," Morgan says.

"No that profile never fit Abbey Taylor. That fit the shooter," Hotch says.

"Well no one besides Jordan knew the real Abbey. The media made her out to be a criminal and she was innocent," Reid says.

"Not exactly, when I was growing up I wanted to be just like my sister and when she died she was always in my mind when I made my decisions," JJ says

"Colby, Jordan is going after Colby," Reid says.

They rush to the interrogation room where Colby was being held but it's empty. They learn that Colby went home to get some clean clothes but she had an officer with her. Colby is in her house and the uniform is lying on the floor unconscious.

"Ms. Cook why are you doing this?" Colby asked her frightened

"Why? Why do you think? 10 years and I'm still walking free. I think that causes for some celebration don't you? Amy Bird?" Jordan says.

"Abbey?" Colby says in disbelief. "We buried you," she says in a whisper.

"Oh you did. I made sure that stupid bitch was in the ground," Cook says while laughing.

"Jordan? Andrew was right," Colby whispers.

"Yeah he was but no one listened to him," she says while smiling an evil smile.

"But how? You killed yourself," Colby cried.

"It's amazing what you can find on the internet even back then. Its kind crazy that the place I'd plan on carrying out my remembrance is the place where you would be. Now I'd say it was fate," she says hitting Colby with her gun making her fall to the ground.

"I knew Abbey didn't do it but I never believed Andrew's story. You have the missing security videos too don't you?" Colby asks her.

"Now that is one piece of this crazy puzzle that I don't hold. I never took the videos. But I'll dwell on the some other time. Now say night night Amy Bird time to visit Abbey," Cook says as she cocks the gun ready to shoot. The team busts in and takes her down. She is arrested and charged with 8 counts of murder in the first degree, 1 count of attempted murder, assaulting a police officer, and faking her own death. Abbey Taylor is clear of all charges against her. Abbey's family is given a pardon from the president.

Andrew is seen going into his apartment and pulling out an old box from under his bed. Inside is a VHS tape and a year book from Xavier. Then the screen goes blank.
