Chapter 2 - No Regrets Part 2

"This candle ever gonna go out?" Otis shouted over the roar of the flames.

Herrmann replied "That propane's gotta go somewhere. If it goes out then we got to worry."

"Chief, the pressure's falling on the pumper."

Boden went over to the truck to assess the damage for himself and saw that it wasn't good. "Son of a bitch. Collins, the Seals just popped, we've lost pressure."

"Herrmann, set up an Ariel pipe, we've got to squeeze every bit of water onto that tanker or it'll blow." Kensi said.

"Got it, let's go! Get out of here!"

They worked quickly and soon the pipe was set and ready to go. "Here comes the water, Lieutenant!"

"Let's hope it's enough." she said as she watched Boden and Mills disappear into the warehouse to look for the missing workers. "Casey, any luck?"

"No, I'm still looking."

"Do you need-"

"No, no, no." Cruz said from atop the truck as the pressure on the Ariel pipe began to fade. "That's it on the water. Engines fried, watch that tanker!"

"Chief, the heat destroyed the pressure release valve." Severide said into his walkie. "What do you want us to do?"

"That tanker's gonna blow and is going to take the block with it." Boden paused. "This is battalion 25 to all fire and police personal. Evacuate the area to a 1/4 mile perimeter. Repeat, evacuate the area.

"I'm going to need confirmation that all personal have pulled back to a safe distance."

Mackenzie sighed and shook her head upon hearing her chief's orders. And knew that this was one she was going to break. "No. I'm not leaving."

"I've got a job to finish." Casey said in agreement. "Kensi, with me."

Severide said that his team would cover the tanker and Kensi went to aid Casey's search for Anna.

"Uh, negative on that confirmation, Chief." Herrmann said.

"Anna!" Casey called out as he made his way into another car. He searched high and low with Collins doing the same on the other side.

"Anna, can you hear me?" Kensi looked under the seats and beneath luggage but found no sign of the young girl.

"Anna?" Casey made his way to the back of the car and saw a backpack and then part of a sweater.

"I don't see her, Casey." Matt lowered his head at the sight of a woman who didn't make it, and nodded before following Collins out of the car.

"Keep looking, I'm going to go see if her Dad knows where else she might be."

"Alright." Mackenzie searched under the car they just searched and the surrounding area. Still she didn't see the girl in the stripped sweater. Not even twenty seconds had passed before Matt came running over, pointing to a car that meters away.

"She's not here!" Kensi said as they reached the back of the car.

"Wait," Casey said as her peered through the back of the train car. "there."

"Anna!" the two lieutenant's ran over to a pile of gravel where the girl lay, unmoving.

Mackenzie pulled her gloves off and knelt down beside the girl to feel for a pulse. "Anna, can you hear me?"

"I need a backboard over here!"

"C'mon Anna. Open your eyes for me." Kensi gently shook the girl until she slowly opened her eyes.

"My dad?" she mumbled as she looked at the two firefighters.

A smile of relief washed over their faces. "He's waiting for you." Casey says.

Finally a backboard was brought over to take Anna to see her father and get the treatment she needed. Casey and Collins walked back to join the others when Chief Boden motioned them over. "You disobeyed orders."

"Yep. I suppose you taught us that." Casey says. "Chief, if it were up to me, you wouldn't be going anywhere."

"Thanks." Boden clapped Casey on the shoulder and then left.

"First day at 51," Casey and Kensi walked over to the trucks as they were finishing up. "not too bad."

Mackenzie laughed. "Yeah. It was something alright."

The ride back to the house was quite as everyone was lost in their own thoughts. When the trucks pulled to a stop, they filed out and was met with the presence of a woman in a green coat. A scowl instantly appeared on Kensi's face at the sight of Gail McLeod-the woman who shut down her firehouse.

"That was some good work out there today." she said as Chief Boden walked up to her. "It's calls like that that reflect well on this house."

"I don't give a damn about how it reflects. We can't operate without the support that we need."

"But you did today, didn't you? You worked with what you had and you saved lives." McLeod said with a smile. "With, might I add, a new lieutenant who had just arrived today.

"So whether you like it or not chief, the system works. But that's not your problem anymore." McLeod handed Chief Boden a folder, a smirk on her face. "This is for your exit interview tomorrow. Please fill it out and remember to bring your badge."

Morning came to find Mackenzie standing in front of her locker as the end of her shift neared. She held a photo of her Aunt Kelsey and herself standing in front of the firehouse the middle of her senior year of high school.

"I miss you so much," she murmured to herself as she taped the photo onto her locker door.

"Hey, Collins."

Kensi turned to face Dawson who was standing a few feet away. "Hey."

"A few of us are going to Molly's. We'd love for you to join us."

"Can't. I have some things I need to finished." Kensi said as she closed her locker. Grabbing her duffle bag she walks pass the paramedic. "Maybe next time."

"Yeah. Yeah, sure." Dawson replies.

Kensi says goodbye and takes her leave, stopping by Casey's office for a few seconds. Gabby shook her head as the two lieutenants talked briefly before hugging and going their separate ways.

As Collins made her way to her car, her cell began to ring. Removing it from her back pocket, she sighed as the number she recognized was shown on her screen. Pressing IGNORE, she unlocked her car and started the engine, wanting to get home after the previous days events.

Fifteen minutes later she pulled to a halt in front of her apartment. She had just unlocked her front door when she heard someone come up behind her.

"Mack!"

"Go away, David." she said without looking back as she drops her bag inside.

"Why haven't you been answering my calls?"

"Because we're over. I told you that."

David walked closer to Kensi, stopping just below her steps. "I just want another chance. Please? I know I made a mistake and-"

"I gave you another chance, and you blew it." she cuts him off as she heads inside.

"Mack-"

"Leave, David. Or I'm calling the cops."

Mackenzie shuts the door harder than necessary and fidgets with the lock for a few seconds before it finally turns. Thank goodness Casey had some spare time to come over and fix it for her later that day. She didn't want to think about David getting into her house because of a broken lock.

It was early evening when a knock sounded on her door. Kensi was in the middle of removing her dinner from the oven before she jogged to answer the door. "Hey, Casey. Thanks for coming." she greeted and ushered him in.

"No problem, Kenny." Casey says with a smile as he sets his bag of tools down. "You said it was the door?"

"Yeah, the lock actually. It jams more often than not."

"Huh," getting a better look where Mackenzie mentioned, Matt sighed. "The bolt is dented."

"What?"

"Here, feel that?" Kensi runs her fingers over the bolt and nods her head. "Any idea how that could have happened?"

"No clue," she replies, when in reality the only way something like that could have happened would have been by David just last week. Had he really tried to break into her house?

"Well, you'll need a new lock for sure. I can go to the store and stop by after shift to install it for you."

"I'd appreciate that." Mackenzie heads to the back to the kitchen and grabs a drink from the fridge. "Would you like to stay for dinner? Maybe fill me in on some need-to-knows with 51?"

"Sure."

They talked and caught up for the next couple of hours their meal before Casey left. "I'm glad you're at 51, Kensi."

Mackenzie smiled and pulled Casey into a hug. "Yeah, me too. Goodnight, Matt."

"Night."

The rest of the evening went by slowly with Mackenzie going over the reassignment papers that she needed to turn in the next day before shift and cleaning the kitchen. After she took a shower, she decided to unwind with catching up on some shows that were on her DVR.

When her eyelids became too heavy to ignore, Collins crawled into her bed and pulled the warm covers tight around her body, falling asleep seconds later.

There is the end of episode 2x07. I'm working on 2x08 now and I'll be adding my own call to it, so I hope you stay for that.

Thanks again for the nice response to this story. Please take a few seconds to leave a review. I read and respond to them all (if I can) and they mean a lot to me as a writer.

Merry Christmas! xo
