"I've got four names on the bottom of the list Prentiss gave us" Morgan said as he stuck a fluorescent yellow post-it note onto the board for the case they were working. "Luke Renault, Laurence Riley, Lola Raferdy and Lilah Rogers.

"They all have the same initials?" Seaver asked.

"The CIA uses cryptograms like these to help undercover agents identify other agents on the same case" Hotch said as he walked towards them. Reid looked up when he saw him talk but he was still deep in thought.

"So, the last four names are spies?" Seaver said, and stood up to take a closer look.

"It looks like it" Morgan said as he passed the names to Seaver. She glanced over the names, nodded slowly and went to pass the sheet back to him.

"Wait, can I see that?" Garcia said as she reached across and took the paper. She studied the names for a moment then looked up. "This isn't right. You see that space at the bottom?" she said as she held up the piece of paper to show the team. "That shouldn't be there"

"Couldn't it be a formatting error?" Rossi asked as he leant against one of the desks.

"No, this is a spreadsheet template. The formatting doesn't allow for this" she said and passed the paper to Hotch. He glanced over the listen then looked back up at Garcia. "There's a missing name" she said as she took the piece of paper back.

"So, another spy covering his LR?" Hotch said and crossed his arms. Reid took a step back as he started to remember the phone conversation he'd heard Emily have the day before.

"Oh my God" he whispered under his breath.

"What's wrong?" Hotch said as he turned and trained his eyes on Reid.

"Lauren Reynolds…" Reid said his voice drifting off towards the end.

"Who?" Morgan said as he looked away from the board and towards Reid.

"Lauren Reynolds is dead. Emily said that on a phone call yesterday, she said that she was an old college friend but she didn't seem to be upset… it was like she was reminding herself" He said as he looked at the shocked faces that surrounded him. "Lauren Reynolds- LR" he said louder as he tried to convince himself he was right.

"If Prentiss is the last name on that list that puts her on Doyle's list too" Seaver said as she looked over at the board again.

Hotch moved away from the board and looked at Emily's desk. He pulled open the top draw and picked up her gun and badge.

"She left behind her gun and badge? Why would she do that?" Morgan said from by the board as all the eyes were trained on Hotch.

"She's running" Hotch said and dropped both items back into the draw and slammed it shut.

"Why would she run? We're her family, we can help" Reid said his voice crackling as he fought hard to keep back tears.

"Doyle's killing families, Reid. She knew if she stayed that Doyle was going to come after us… she ran to protect us" Rossi said, the last sentence barely above a whisper as they all realized what this all really meant.

"But we could have helped her" Reid whispered as he scuffed his foot against the floor in anger. He knew she hadn't just run to protect the team, she'd run to protect him too.

"She's a trained spy who doesn't want to be found" Rossi said as he stood up straight and looked to Hotch.

"She knows everything about us but we know nothing about her" Morgan said, his voice saturated in anger.

"Then how do we find her?" Garcia asked, she was obviously distraught.

"We treat it like any other case. Ian Doyle is our UnSub, Prentiss is the victim. Because terrorism isn't an area we specialise in I'm bringing in an expert for this case who should also be able to shed some light on Prentiss's past" Hotch said in his monotone voice.

"Who?" Morgan said as he looked hard at Hotch.

"Me" JJ said as she walked up from behind them. All of the team turned round and gave warm smiles to her, all except Reid who sat where he was as he struggled to fight back more tears.

"We all meet in the briefing room in 10" Hotch said, he walked closer to Reid and whispered so no one else could hear "take a minute if you need to" then walked back to his office.

Reid quickly walked over to his desk and picked up the photo he had been looking at last night, that was now face down on the desk, and walked back to the empty briefing room. He walked to one of the windows as he let one tear escape from his eye.

"Spence?" JJ said as she slowly opened the briefing room door. Reid hurriedly pushed the tear aside, turned round and tried to act as natural as possible.

"Hey, JJ. I was just, uh…" Reid began, unsure of what to say.

"You don't have to explain anything to me, Spence" she said, slowly walked over and touched his hand. She knew better than anyone what he needed right now was a friend.

"I don't know why she ran away… We could have helped her…" he said as another tear escaped from his eyes. "I could have helped her" he said and roughly pushed the tear away.

"She ran to protect us, Spence. She didn't want us to help her because she knew it would put us in danger" she said and softly rubbed his arm in an attempt to comfort him.

"You don't understand" he said as two more tears fell but he didn't bother wiping them away this time. "We were living together. I should have seen what was happening… I should have helped her" he said as a flood of tears followed.

"Were you…?" JJ paused, unsure of how to put it.

"Two years… I took her to Las Vegas in the summer because I knew we wouldn't be able to do anything for our anniversary in September" he whispered and showed her the picture. "What if she knew about Doyle then?" He said and started to cry harder. JJ wrapped her arms around him and let him cry into her shoulder because she knew that's what he needed. He didn't need to be told it was going to be ok or Emily was fine, he needed to cry because that was the only thing that was going to make him feel better.

Reid gently lifted his head off JJ's shoulder and wiped away a few of his tears. "She looks happy there, Spence. She doesn't look worried, she looks comfortable and in love" She said and handed him back the photo.

Reid smiled when she said love; it had been there dream to tell everyone about their relationship. They were thinking about telling them all just after their anniversary but when JJ left and Christmas round the corner they had put it off, they had promised each other the team would know before their 3rd anniversary. Well, he kept that promise… but not under the circumstances they had wanted.

He gently stroked the photo over and over then looked up; JJ was looking at him with that sad smile he rarely ever saw. "I, um, I'll go put this back… the team will be here soon" he said in a rush of words as he pushed the last tears from his face.

As he walked past the desks he could tell they knew he had been crying, his eyes were probably red and puffy and his cheeks might still have a bit of moisture from the tears. He quickly sat down at his chair and pulled the bottom draw open, he was going to put it back but what was the point if everyone knew? He wanted to have a nice frame for it, to be able to have it on the side and look over at it whenever he felt sad.

He closed the bottom draw and lent the picture against a few files, he didn't have a nice frame for it like he wanted but he had the picture and that was all that mattered.
