Hotch, Rossi, and JJ left. Penelope grabbed her laptop and went into her bedroom.

"What is she doin' in there?" Morgan asked.

"Do you really want to know?" Emily countered.

Gwen sat with Spencer on the couch.

"Earlier...with your father..." Spencer started.

Gwen knew where he was going with this. "When I was growing up, my father may or may not have used interrogation techniques to catch me in lies. I was a bit of a rebel. Never broke the law or anything, but I did enjoy getting into trouble."

Spencer smiled.

"What?" Gwen asked.

"Nothing. Just trying to picture you as a teenager."

"Come over some time and I'll show you pictures."

Spencer blushed. Thankfully, Penelope's printer started printing, saving Spencer from having to sputter out a response.

Penelope came out of her bedroom as Derek grabbed the papers. "Those are all the cases I flagged," she told him.

Derek handed them each a few sheets of paper. "Okay. Everybody take a copy. We need to see if any of the agents overlap in all of the cases."

"There aren't any agents working on these cases. But the same deputy was a first responder in three," Emily said.

"What's the name?" Derek asked.

"Jason Clarke Battle."

"What are the cases?" Spencer asked.

"Uh, all three were drive-bys, at close range, shot with a revolver."

"Just like Penelope," Gwen said.

Penelope brought up her search program on her TV and typed in Jason Clarke Battle. A picture of a man popped up and Penelope visibly froze.

"Is that him?" Emily asked.

"Yeah."

"He's been honored twice as a hero."

"So why's he stuck at deputy?"

"Because even to his superiors, something was off about him."

"Makes sense. The showy clothes, the subtle bragging. He presents himself as a prominent attorney when he's actually just a deputy sheriff."

"Underappreciated in the world and over appreciated in his own mind."

Spencer looked at Gwen and could see the gears turning in her head. "Gwen, what is it?"

"Angel of Death."

"What?" Penelope asked.

"He's an Angel of Death."

"I thought those were nurses who put people out of their misery."

"Yeah, that's one model. The other is someone who puts people at risk in order to save them," Spencer explained.

"So he shot them so that he could save them?"

"Yeah. And when he couldn't, he made it look like a random murder," Emily said, "It's how he was able to be the first responder."

"It's called hero homicide complex. It's most commonly found in firemen who set fires in order to save the day," Spencer added.

"Garcia. You flagged these cases. He thought you were onto him," Derek told her.

"I wasn't."

"But you're the only person in the world who was gonna make the connection. In his mind, he had to eliminate you," Emily said.

Penelope took a deep breath and leaned back into her couch.

Gwen sat next to her and rubbed her arm. "Just breathe, Penelope. We'll get this guy and then you can go back to being your normal sparkly self."

Derek got the phone with the police department. "Deputy Battle, please. Okay, what time is his shift over? No, no message. Thank you." He hung up. "Okay, so he didn't sign out to a location. His shift is over at midnight. Until then, I do not want this guy knowing that we are onto him."

"Why? What's the profile say?" Penelope asked.

"He'll keep getting bolder trying to cover his tracks. And if that doesn't work, he'll die shooting," Spencer said.

Something popped up on Penelope's screen. "Okay. That's funky."

"What's going on?" Spencer asked.

"He just logged into my system. There's a link up on my screen."

"Maybe it's a mistake," Emily said.

"No. He's good. He's not careless."

"Could he be trying to show you something?" Spencer asked.

"He could be baiting me."

"What do you mean?" Emily asked.

"If he's with internal affairs and I follow his lead, whosever login I use could lose their job."

"What's your gut say?" Derek asked.

"He's a hacker. We have a code."

"You trust it?"

"I have to."

"Do it. Make contact."

Penelope made contact with the hacker on the other end and he gave her access to the cameras at the BAU.

"It's the BAU," Emily realized.

"God, that's him," Penelope gasped.

Morgan got Hotch on the phone. "Hotch, it's Morgan. He's in the BAU. Deputy Sheriff, mid-bullpen, just past my desk. Got him? Don't let him know we're onto him. He's a classic narcissist with a hero homicide complex, and he's spiraling. If you let him know we're onto him, he's gonna start shooting."

All they could do was watch.

"We gotta slip someone in behind him," Derek said.

"Can you get us the cameras outside the bullpen?" Spencer asked.

They flipped through the cameras until they saw JJ in her office.

"Oh, my girl," Penelope gasped.

Derek dialed JJ's number and they watched her pick up. "JJ, it's Morgan. Listen to me. Listen to me very carefully."

After explaining to JJ what was going on, they flipped back to the bullpen camera. They watched as Battle's body language changed.

"He knows they know," Emily said.

"This is crazy. We gotta get over there," Derek told them.

"I'm going with you," Penelope said.

"No, you are not."

"You do not have time to argue."

Gwen helped Penelope up and they piled into the FBI SUV. Gwen shared a look with Spencer, who nodded. He wasn't going to try and stop her.

In the end, they arrived shortly after JJ was forced to shoot Battle.

Gwen rushed over to her father and hugged him as he muttered some comforting words in Italian. Logically she knew he was never in any danger, but her greatest fear was losing him and not being able to say goodbye.

Spencer approached them once Rossi had calmed Gwen down.

"Make sure she gets home safe," Rossi told him.

"Yes, sir."

Spencer wrapped an arm around her waist and led her to his car. When they got to her apartment building, he parked next to the curb.

They sat there in silence, both not quite knowing what to do.

Spencer cleared his throat. "Oh, um. I figured you'd want this back." He pulled out her Pentagram and handed it to her.

"Thank you, Spencer." Gwen leaned over and placed a soft kiss on Spencer's cheek, before getting out of the car.

Spencer touched the spot on his cheek she had kissed and smiled.

Gwen's heart was thudding in her chest as she rode the elevator up to her apartment.

Had she really kissed Spencer on the cheek? And why was thinking about how nice it would be to feel his lips on hers?
