Reid was shaken and looked trouble when he reached Rossi's room. Without thinking twice he barged into the room to get Morgan and Rossi's attention. Looking at Reid's flustered face, both agents knew that something was wrong.

"What is it Reid?" Rossi asked quietly.

He and Morgan looked at the young genius trying to remain calm as they didn't want to scare Jack who was playing a transformer robot nearby.

The young agent told them about the box.

"Morgan's credentials as well as Hotch's were in it. There are blood stains on them," he said. Reid also told them about a third item inside the box which was a mysterious clear liquid vial.

"Is there a note?," Morgan asked.

Reid nodded and read it out:"Time can bring you down, Time can bend your knees. Time can break your heart." The two agents looked at him with a baffled look on their faces.

"I know these words. They sound so familiar," Reid told them. He called Garcia, who had gone back to her office, and asked her to do a search on them online.

The tech analyst's fingers flew on the keyboard as she keyed in the three phrases.

"Ok...They are several possibilities here including they could be taken from books and songs," Garcia told them through the phone speaker.

"Garcia, narrowed down the search to song lyrics which have all three of them. The sentence structure is more like a lyric of a song," Reid said.

"Bingo! They are from from Eric Clapton's song entitled Tears in Heaven". The full version of the lyrics have been sent to your PDAs," she said before hanging up the call.

They left Rossi's room and gathered at the briefing room. Reid put up the song lyric on the plasma.

"What does it mean aside from it is a sad song?" Morgan asked.

Reid told them the singer composed the song following the death of his son.

"Maybe, we should look at past cases involving those who have lost their sons," the young genius added.

At the factory

Hotch tried to recall Michael's profile so that he could try using it in his attempt to escape.

"Michael, your son will not want you to do this."

"What do you know about what my son wants. He's dead, thanks to you. You call his father a child's killer. You can never understand. I love the three girls. They have suffered so much in this life so I put them out of their misery. What so wrong about that?"

"You took their lives and they didn't ask for it," Hotch replied.

"They didn't know anything. They were young. But, I know what was best for them," said Michael, who was busy filling the syringe with the clear liquid again. Hotch saw the syringe and knew he would go through another episode of extreme pain. The BAU chief wondered how much more his battered body could endure the pain.

Back to the BAU

Garcia managed to narrow down two cases which involved unsubs who had lost a son.

The two cases with the pictures of the unsubs were displayed on the plasma and the files were distributed to each team member.

"The first involved a female unsub whose son was found drowned in a bathtub. She's still serving time in the Federal Correctional Institution Tuscon for killing her husband," said Prentiss as she read the case file.

Morgan pointed out that the second case involved Michael Stanton the IV who was found guilty killing three girls. But, he noted that the man had been listed as dead in prison.

"It says here that his body was found burnt beyond recognition in a freak fire inside his cell one day," he added.

Rossi asked whether Michael's body had been identified to be his, Reid replied that the prison doctor had made the identification.

"Was there a DNA test?", Rossi asked as he looked through the thick file.

Reid who could read faster than everyone in the team said he could not find the report of any DNA testing.

JJ immediately picked up the phone and called the Tuscon correctional institution and asked for the prison doctor.

Her grim look showed that she wasn't happy listening to what the other person was saying at the other end.

When she put down the phone, all eyes were on her and she informed them that the prison doctor was killed in his home few days later after Michael's death.

"What if he's not dead," said Prentiss.

She said it was too much of a coincidence that the only doctor who had identified Michael's remain was dead.

"It doesn't feel right," she said.

Rossi agreed with her. He assigned Prentiss and JJ to go to Arizona and check out the incident.

In the old factory

Hotch tried to distract his kidnapper by keeping him busy talking about his son.

"Michael. Tell me about Adam," Hotch asked.

"Why?", he replied.

"You told me that I don't know anything about your son. Please tell me about Adam. I want to know more about him," Hotch said.

Michael put down the syringe and pulled a chair. He sat down and gave Hotch an intense look.

"He was a great boy. I would always read to him at night and his favourite book was `A Tale of Two Cities'."

He continued talking about Adam for few minutes with a far away look on his face.

As the unsub was busy telling him about his dead son, Hotch desperately tried to loosen the rope around his bloodied wrist and suddenly his hands were freed. He kept his hands behind him and would act when the time was right.
