"What are we waiting for? Let's get to work on what Kayla meant by that!" Morgan exclaimed. Emily and Jack shared a look. "We already know what she's talking about."

In the train:

Mikhail decided to see what was going outside again. Now he could see the man who worked for someone, and saw that his boss had arrived too. The inferior- he saw was a man he had often met- at the support group- Albert Ivanov. The boss, he could not see, was wearing a ski mask. He messaged all this to the number he had been contacted from.

"When we had had that midnight meeting, Reid and Kayla had stayed behind and told their suspicions about Nikolai Petrov. Among the people from the support group, Nikolai's name was there too, but Kayla and Reid did not tell anyone right away, because at that time, we did not have any forensic evidence that could put Nikolai behind bars, and revealing that information would put him on the guard. He fits the profile- when he mentioned he had come to America for university, he had been staying at his late grandfather's house, his grandfather, who had left him. He was independant, became a police officer. Then at Mark Berns' crime scene, Kayla deducted that the man was approximately 5'10, and had an SUV. Nikolai's police car is an SUV." Jack told them as everyone stared at him dumbfounded.

"He just left here." Morgan told him wide-eyed. "I know. I placed a tracker on him. I know exactly where he is." Emily told with a tired smile. Morgan raised his eyebrows, "Where is he?" Emily sighed and nodded towards the train, "In there. It fits with the message Mikhail just sent us."

"So what do we do now? You could have told us, you know?! We could've prevented this from happening!" JJ yelled, "Now Reid's stuck in there!" she was near to tears. "You knew it was Nikolai. Why didn't you tell us?" Morgan asked her in a not-calm voice. "Because that would've meant that we have no proof against him. Emily and Jack were trying to catch a criminal here!" Rossi said defending his friend and surrogate daughter. "You guys know better than anyone that we had to do this. JJ- you suggested baiting him yourself."

"So if he knew we were baiting him, why did he attack?" JJ asked, now calm.

"He wasn't getting the attention. His seniors did not want any involvement of media in this. He wanted to create this stalemate position. If we move our piece, he'll kill Reid and Kayla, if he moves his, he'll be dead" Matt said, gesturing to the snipers who had now surrounded the train, "and, he'll get media attention anyways.

"So now that we are in a stalemate, what do we do? Mae asked.

Emily and Jack shared a look and smiled evilly. "Oh no. We aren't in a stalemate. We just checkmated him." Emily said with a smug face. "When Reid and Kayla told us, we planted something on him. We tell him to return Reid and Kayla, give us the location of Mark Berns' son and ex-wife, otherwise- ka-boom!"

"Nikolai Petrov!" Morgan said through the speaker, "We know that it's you. It is not too late to turn back now! Send both of our agents back now, and tell us where Mark Berns' son and ex-wife are."

Nikolai Petrov replied from inside, "I seem to have lost my hearing! Why would I do that?! I made the second to last mistake by calling you here. I win!" and more evil-witch cackling.

Inside the train, Reid smiled- things were going according to the plan- only Kayla had got hurt badly. Reid hoped she woke up. He heard Morgan further say. "Oh no, Petrov. If you value your life, you will do as we ask. Otherwise, ka-boom!"as if on cue, a small explosion lit up one side of the train car. "The next explosion, Petrov, will be ON you."

Nikolai started gasping and muttering gibberish under his breath, then grabbing the speaker, he yelled, "OK! OK! You win!"

"One bruised eye and sprained wrist. You got off easy." Mae told Reid as he and Kayla sat in the back of a police car trying desparately to get rid of Mae's shock blanket. "Don't resist the blanket and stuff." He heard Kayla say suddenly beside him. "Use it for sympathy." Reid gave her an amused grin. "Get some special treatment. What's wrong in that?" Reid smiled and said, "It's a little rough. Besides, I like the one with foil better." Kayla laughed, then stuck her tongue out for Mae who was now examining her. "Kids- let's just get home." Mae told them, "what are your plans? I was thinking of having some fun now that everything is over." Reid sighed. "Yeah. But what happened to the son and ex-wife?"

"The son and ex-wife were found at Nikolai's house." Jack said joining in the conversation. "They are at the hospital as we speak. As for Mae, I think all of us are going to join in on that fun."

Reid and Kayla looked at Nikolai and his accessory in crime, Albert Ivanov being led away in cuffs. Kayla walked towards Nikolai and said, "You see, Nikolai- you did not make the second to last mistake- you made the last one- calling the IRT and BAU. We're kind of experts at kicking criminal ass."
