A/N: Hey Rookie Blue Fans! I just wanted to address a question raised in the comments pertaining to my portrayal of the command structure in 15. In real life, detectives would report to their own Detective Sergeant, not the Staff Sergeant of the division. However, in Rookie Blue, there are numerous instances of Staff Sgt.'s Boyko, Best, and Shaw commanding detectives (Best overruling Blackstone, Shaw benching Peck). So, for the sake of maintaining continuity with the show, I kept this general chain of command rather then create new characters to fill a position that was only mentioned once the whole show, (the last minute of the last episode.) I hope this clears my decision up for the guest in the comments and for anyone else who may have been wondering. Anyway, back to the story!

A few months later..

"15 Sierra 3, attend 1519's position to assist with a traffic stop."

Andy grabbed her receiver from the center console, "S3 responding." Andy looked up on her computer the location of their stop and went in that direction, lights no sirens, save for an occasional bloop or wail to get traffic moving a little better.

A week back on the job now and she felt like she hadn't missed a beat since coming back. And, of course, she beat the doctor's estimates on recovery and rehab to get back a little sooner. So here she was, cruising through downtown in her new truck, to replace the totaled one, lights flashing and siren wailing on her way to a call. What could be better?

Andy wasn't the only one to get new wheels. While she was gone, the city's effort to overhaul the Service's fleet finally reached 15. Most of the Crown Vics have been replaced by Ford's new Police Interceptors and the Tahoes phased out in favor of Ford's Police Interceptor Utility, which was what Andy was driving. She liked it, it was much sleeker than the bulky Tahoe. The new cars were the same way compared to the Crown Victorias.

A couple minutes later she came up on 1519. Today it was occupied by Diaz and Foxx, who had recovered from the stabbing and been back on the job for a couple months now. She pulled up behind them and left her flashers while muting the siren before exiting the truck. Diaz and Foxx were in a ready stance, crouched behind their respective doors, hands on their holsters.

Andy duckwalked up behind Diaz and asked what was going on.

"It just escalated," he said back to her without taking his eyes off the car. The plates are registered to a guy that's been reported missing. Initially and we got a bad vibe from the driver, didn't have a license, but gave us a work badge with a name on it.

"And?"

"That name matches up to a POI in an outstanding assault with a deadly weapon investigation, so we called four your assist."

"Is it him?"

"Her, actually. And yeah, the ID and the picture on file look pretty similar."

"Okay, did she resist the traffic stop."

"Not really she was a little hesitant on where to pull over but nothing major."

"So, the concern is that the deadly weapon may be in the car? What was it?"

"Allegedly some guy was stabbed multiple times. He's still in the hospital, I guess. Don't know if she's a witness or anything more. And there's apparently a weapon in the car."

"What do you mean?"

"After we called for you, while we were waiting, she called into 911 and threatened to kill herself if we tried to arrest her. She says she's holding a knife to her throat right now and has a gun that she'll use on us if we try to approach at all."

"Damn, what's her name?"

"Cynthia Perez."

"Okay, give me a minute." She went back to her truck and pulled up her computer and ran the name to get any other useful information she could gather quickly then radioed to dispatch. "Dispatch, 15S3, I'm at the felony traffic stop with 1519, advise further responding units to keep a distance in light of the developments. Also, request ETF and a negotiator."

"Copy 15S3."

Andy got back out and moved back to her spot behind and to the left of Diaz. "Could you see any weapons when you approached?"

"No, I didn't. Jake, you see any weapons when we made initial contact?"

"Negative, I don't think so."

"So, we can't even confirm the presence of a weapon. But we also can't confirm there isn't one. For now, we operate under the assumption there is." She grabbed her shoulder radio and contacted dispatch again. "15S3, can we get a perimeter set up, at least a block in each direction with us at the center of the square."

"I'll assign further units, Sergeant."

"What are we doing?", Chris asked.

"We're waiting, waiting for ETF. We let them handle this. Until then we just make sure this doesn't escalate anymore."

Within 15 minutes the perimeter was in place and ETF was on location. Andy eagerly relinquished scene command over to Bailey.

"What's the plan?", Andy asked him.

"Well, right now, we're trying to establish a means of communication for the negotiator. While that's getting worked on, we have a scout getting up in that tower," he pointed to a skyscraper at their 11 o'clock. "He's got a scope so hopefully he'll be able to confirm or deny a weapon."

Andy nodded and waited for something to happen. She was standing beside the command truck with Bailey. Inside was the negotiator and a couple techs. After a couple minutes Bailey's radio went off.

"Alpha 1, go"

"Alpha Romeo, I'm in position, view positive."

"Roger." Bailey said to Andy, "That's our scout." He's got eyes on.

"Can he confirm weapons?"

"Confirm threat, Alpha Romeo."

"Threat positive. Subject holding knife up, near neck. No visual on gun."

"Hold position Alpha Romeo." Back to Andy Bailey said, "So we can't make an approach. Did you get anything on the subject?"

"Yeah," Andy pulled out her notebook. "Name is Cynthia Perez, 26, form the city. Only family on file is a mother. She's a POI in a ADW case. Clean record otherwise. Car came back stolen, that's why my officers pulled her over and why I got called in." Bailey knew the rest about the 911 call and suicide threat.

"Okay, I'll get that to the negotiator, hopefully they can get a line of communication open soon." Went inside the truck and updated the negotiator with that information. They got an update on his progress, or lack thereof, as well."

"So far," the negotiator whose name plate said Sands was saying, "She hasn't answered her mobile line." We can't approach with a phone and I doubt she'd be willing to come out and get one."

Bailey said, "So you're telling me we're nowhere."

"Hey," Sands held up both palms. "You know as well as I do that communication and negotiation is a two-way street. I mean, I could pull out the bullhorn and start yelling but that and peaceful resolution don't go together."

"Alright," Bailey conceded, "keep trying her mobile phone. Sergeant McNally, figure out how to reach her Mother, maybe she can help us."

Andy left the command truck and went back to her truck that she had backed up to the police line. Diaz and Foxx had done the same with their car. "Any progress, Sarge?", Jake asked optimistically.

Andy sighed, "No. They haven't been able to get Cynthia to answer her phone. I'm going to reach out to her mother, we're probably going to need her here."

"We can go get her," Jake offered.

Andy was about to say something but Chris spoke first. "Can't. We made first contact so we need to stay on scene."

Foxx nodded in understanding.

"What he said. Thanks for the offer, though," Andy said. She climbed in her truck and pulled up Cynthia's file on her computer, linked to her mother and got the address and contact information. She pulled out her phone and dialed the number. It rang a couple times before an unsure voice picked up.

"Hello?"

"Ms. Perez? I'm Sergeant McNally, Metro Police." Andy explained the situation and tried to reassure her before asking if she could send a couple officers by to pick her up and bring her down here. Then she called Chloe.

"Price," Chloe answered

"It's Andy. Listen, who're you riding with today?"

"Marcy. Why?"

"Perfect. You guys know what we're dealing with, right?"

"Yeah, somebody holding herself hostage, or something."

"Pretty much. We're calling her phone but she's not answering yet. Could you guys swing by her mom's and bring her down here."

"Yeah, no problem."

"Great, I'll text you the address. Her name is Martha Perez. And I don't know why, but she seemed kind of hostile."

"Understood."

Chloe and Marcy pulled up in front of a pleasant looking house in a quiet neighborhood. Walking up to the porch, the front door opened and a woman hurriedly stepped out.

"Ms. Perez?", Chloe asked.

"Yes, you're going to take me to my daughter?"

"We're going to take you to the scene, yes. I'm officer Price, this is Officer Zettle. Follow us, please." They helped Ms. Perez into the car and then took off.

Marcy drove while Chloe talked with Ms. Perez. "Ms. Perez when we get to the scene we are going to take you to our sergeant, Sergeant McNally."

"Yes, I spoke with her on the phone."

"Right, we'll take you to her and she can fill you in with more information and if they need you to do anything."

"I understand."

Chloe knew Ms. Perez wasn't in a talkative mood but she still tried, "Ma'am have you ever suspected that she may be suicidal?"

She shook her head, "Never, no. But, since her brother last year, she's been a little more distant."

"What happened to her brother?"

"You killed him," Ms. Perez said sternly.

Now Chloe understood why Ms. Perez was so resistant to talk and why Andy thought she was a little hostile. "Does she have a boyfriend, or a girlfriend?"

"She's had boyfriends but they come and go. I don't know about right now. She doesn't talk about that too often."

"Okay, well, if anything else useful comes up, you can tell it to Sergeant McNally." The rest of the car was silent, and all involved were happy when it was over.

When they got to the scene Chloe and Marcy led Martha to Andy and then they left. Martha went over what she and Chloe had already talked about on the way there. "I'm sorry to hear about your son. And you probably think I'm just saying that, but it's true," Andy said. "Right now, Ms. Perez, we're all here to make sure nothing happens to Cynthia or anybody else."

Ms. Perez stared off towards the car her daughter was held up in and nodded.

"I understand, ma'am. Trust me, we all want Cynthia out of there safely. And we think you may be able to help us."

"I will try, but not for you. For my daughter, the only child I have left."

Fair enough, Andy thought. "I'm going to take you over to Seargent Bailey, he's in charge of ETF on scene, and the negotiator that's been trying to contact Cynthia. Any help you can provide will be most useful there."
