They spent the whole night in the round table room, formulating a plan. Locating the server would be difficult, and Cantor could stop them at any second. But proving it existed was a different story.

"Okay, I'm in his files," Garcia said as it got closer to midnight. "And I can tell that there's a missing file path. I go to open a file and it says not found, which means it's been stored in a different location and this is just a shortcut."

"He's been fucking with this system all year," Morgan said. "He's the reason for your badge blocks."

Garcia just nodded. "Yeah, I saw the orders on those about an hour ago," she said. "He had my access frozen multiple times."

Morgan was on his third cup of coffee, and Reid was researching other ways that they could get Cantor. He was reading effortlessly quickly as usual, hands moving down the pages.

"I just need to locate the file path," Garcia said. "I just need to establish a connection…" She trailed off, reaching for her mug of tea. "My fingers hurt," she stated, before going back to typing as quickly as usual.

"I've got to make a call," Rossi said, stepping out of the room and going to his office. Hotch followed, close behind.

"Isn't there anything you can do?" He asked, voice low. "O'Connor is just deputy director. Surely you still have pull with Harrel."

"I can't get at Harrel without going through O'Connor," Rossi said, voice just as low. "Unless we've got something real against him and Cantor."

Hotch sank into a chair, head in his hands.

"We're going to figure this out," Rossi said. "God, I wish Erin were still here."

"Me too," Hotch replied, steepling his fingers. He was so ready for this to be over with, to know that Kate was safe and sound. He was so ready to see her again.

He wondered if he ever would.

Rossi was dialing, and Hotch listened as he spoke. Delicate situation, remember what happened in Chicago, anything you can do for me?

"Emily," Hotch said, starting a little after Rossi hung up. "Oh my god, I'm a fool. We talked about setting up a task force to watch Cantor, but we never actually did it."

"It's not too late," Rossi said. "And she'd have influence that we don't."

Hotch was already dialing her number, and she picked up on the first ring.

"Something has to be terrible for you to call me at 11 at night," she said.

"Yeah," he agreed. "It really does."

"Hotch, Hotch, Hotch," Garcia said, scrambling into Rossi's office. "I accessed the server, and we've good as got him."

"But?" Rossi asked.

"There's nothing there about Kate."

"I'm going to put you on speaker," Hotch said, after he could took a long moment to process. "And then I'll explain everything."

"Emily?" Garcia asked, eyes wide. When Hotch nodded, tears filled her eyes. "Emily, I miss you," she said, loud enough to be heard through the phone.

It was 3 in the morning before they had enough on Cantor, and Emily made some calls. And it was nearly dawn when they talked into the the Director of the FBI's office with enough proof to not only get Cantor fired, but sent to prison.

It was an hour of waiting before Harrel showed up, and she didn't look pleased to see visitors at this hour. "What, no call ahead?" She asked sharply.

"We have an urgent matter," Hotch said.

"I know," she replied, and nodded behind her. Cantor and O'Connor were right there. "You've spent the night hacking a private database, one that I expressly told Cantor to set up. You are aware that there are matters in the FBI above even your paygrade, Agent Rossi?"

If it hadn't been for Emily, they would have been done for, then and there. But she had enough contacts to get everything they needed.

"It's all in this file," Hotch said, handing her the folder.

"I'll humor this," she said. "But only to prove you wrong."

It was then that Emily Prentiss walked in. It was only an eight hour flight from London to Quantico, and she still had more than enough connections to make this work. "Madame Director," she addressed. "If you don't want to sanction Cantor, I will. He's been selling information for years, and Interpol has finally caught up." She leveled her gaze with Cantor, and for the first time in his entire career, Hotch saw Cantor flinch. "You made a mistake, buddy. Don't go after one of the BAU's own, because we will end you."

Harrel was still reading, and she didn't stop until she'd finished. "Take him," she told Emily. "I trust you'll get him what he deserves."

"Oh, I will," she replied.

"O'Connor?" Harrel spoke, and the man flinched. "If I see your fingerprints on any of this, you are done for as well. And there will be a full investigation."

"Madame Director," Hotch said. "If I may, one more moment of your time."

"Speak fast, I have a call with the president in five minutes," she said.

"It's about SSA Callahan," Hotch said.

Cantor spoke, as agents from Interpol were cuffing him. "It's too late for her," he gloated. "Too late."

And Hotch couldn't hold back any longer. He swung around and punched Cantor in the face, full on, something he should have done 22 hours ago.

"Agent Hotchner," Harrel snapped, and he straightened as he turned back to face her. "Control yourself."

"I'll be back to talk later," Emily said. "As soon as I find anything."

Hotch watched as Harrel went into her office, closing the door. Emily left with her agents, and Hotch sank onto the floor, head in his hands.

"Aaron," Rossi insisted. "Get up."

"What's the point?" He asked, looking up at Rossi with a tortured face. "What if I lost her? I barely survived losing Haley, I don't think I can do this twice."

"Do what twice?" Rossi said. "She's not gone."

But Hotch couldn't be convinced. He finally stood and walked back to the BAU with Rossi, where they told a triumphant team that it had worked. They hadn't gotten Kate back yet, however, so their celebration was minimal.

"Our jobs are safe," Hotch said, pausing by the door. "So I suggest everyone go home and get some sleep. I'm going to go and shower, at the very least. Emily will call the instant there's an update."
