AN: Well the next chapter will be the last. I hope you've enjoyed the story so far. This is the last chapter for Kathie. I may do a sequal, we'll see. There's a lot I can do with Kathie's character and Kate and Rick's relationship so we'll see how much time I have for a sequal. Anyways, that's not until tomorrow so enjoy the new chapter :)

Kate and Kathie woke up early the next morning when they heard a knock on the door. They both froze and Zeus started barking. Kathie looked through the peep hole and saw that it was Castle. "Castle what are you doing here?" She said releasing her hair from the towel that was keeping her wet hair. "Wait, stupid question" She said when she saw the coffee. "Kate, writer boy is here for you". She smirked before taking her cup of coffee that he had gotten her and walking into the bathroom to dry her hair.

It seemed like a normal day at Kathleen Beckett's apartment but it wasn't at all. Zeus sniffed Castle's pocket and barked. "Oh, thanks for reminding me buddy". He took out two treats that he had and Zeus sat down, ready to receive them. "Good boy!" Castle said patting his head as he enjoyed his milkbones.

"Kathie, trained him well" Kate said coming out of the guest room.

Rick smiled and handed her her daily morning coffee. "Thank you, but you didn't have to bring me coffee".

"Well I happened to be in the neighborhood". Beckett gave him a look that said she was not buying that at all.

"Why'd you really come here, Castle?"

"To make sure that...we're still on for tonight and that you two were okay".

Kate looked at him for a moment and then nodded. "Yea, we're still on". She then heard the music coming from Kathie's bathroom playing. She was very surprised when she didn't hear Kathie's favorites so she figured she had on her radio instead of plugging in her ipod. She heard Katy Perry singing something about "time to face the music, I'm no longer your muse" and that's when Kate looked at Rick, finally showing the fear in her eyes that she may never see him again after he walked out that door.

"Kate...?"

She stepped towards him and placed her coffee down. "I promise I am going to make it to your loft tonight. But just in case something happens to me during the day I want you to know there's a spare key to my apartment in my desk drawer at the station. Take care of Zeus too. He seems to like you and I know Kathie would like know he's in good hands". She gave him a soft smile.

Rick couldn't think. The love of his life was telling him that he was in charge of her things if she was going to die today. He had tried to protect her from this and it was now happening and he couldn't do anything. He looked into her eyes and saw what she couldn't tell him. That she and Kathie were going after Anna and they might not make it back and they had to do this alone.

"Don't worry. I'll make sure he's taken care of".

She gave him a soft smile and placed her hand in his. The warmth of their skin touching always made her feel calm and safe and that's what she needed right now. "I couldn't of asked for a better partner". She whispered before removing her hand from his. "You should go. I'll see you tonight".

He held in the sigh he wanted to release. He didn't want to leave. This was not how he wanted his possible last moment with Beckett to be like, but he knew he had to let them be. "Looking forward to it". He said before placing a soft kiss on her cheek. If he couldn't feel her lips against his the skin of her cheek would have to do.

"Bye, Rick". She whispered again before closing the door. She sighed as she lent against it. She heard Kathie's voice singing along to Lady Gaga's Bad Romance. Kathie's horrible singing voice always made Kate smile and it didn't fail to do so again today.

It was 11:30 and Kate and Kathie were in the building across from the Starbucks on one of the upper floors. They didn't want Anna to spot them. Kate made sure Kathie had some extra bullets for her gun, her ear piece was functioning, and was protected with her bullet proof vest.

"Kate, I'm fine".

"I know. I just want to make sure. Since I'm not going to the Starbucks with you I need to put my mind at ease that my little sister is safe".

"You'll be right outside across the street if anything goes wrong. I'm planning on playing rough from the start so you don't have to worry about Ms. Nice Beckett coming out and toying with her. We can do that once we get her into a prison cell" She smiled.

Kate brought her sister into her embrace and hugged her tight. "I love you, Kathie. We can do this".

Kathie hugged her sister back. "I love you too and you're damn right we can".

Kathie pulled away from her sister and looked down onto the city. She saw a woman with brown hair walking into the Starbucks. She was right on time. A few minutes later she sat down at the table Ray said she would be sitting at. She opened up a book and began reading it.

Kathie looked at Kate and nodded. "Lets go".

They headed out the back door of the building and Kathie entered the Starbucks from the back door. She saw the woman from behind. She heard Kate in her ear saying that she had eyes on the target and that she was alone.

Kathie took a breath before the look crept on her face, the look of payback and revenge. Kathie quickly walked over to Anna. She didn't even have time to turn around when Kathie pushed her head down onto the table and then pulled her back up by her hair to face her. Seeing that she had accomplished breaking her nose Kathie gave her one of those evil smirks. "Hi Anna"

She was shocked. How did she find her? "Well...I've underestimated you Beckett. How did you find me?" The costumers had made their way to the back exit where Kate had told some of the people running towards her that she was a cop and they were arresting a murderer.

"Lets just say I have friends in high places" She smirked again, but it was soon wiped off her face when Anna elbowed her in the stomach, forcing her to remove the hand that was tugging at her hair.

Anna pulled out her gun "Is Katherine with you?"

Before Kathie could answer she was ducking from the bullet Anna had fired. She heard it pierce the coffee machine. What she wasn't expecting though was the explosion that came with it. Kathie was not letting Anna escape because everyone else was in shock from this explosion. She flung herself over at Anna, who had dropped her gun when she realized what she had just hit and they both went through the side glass window, with help from the force of the explosion. They rolled into the alley, along with the flying glass. Luckily, they picked a day where the street was closed so there wasn't as many people.

Kate was frozen on the side walk across the street when she saw the explosion. She was not expecting that at all. "Everyone stay calm, NYPD! Kathie! Are you okay?" Kate whispered into the ear piece. Their plan was for Anna not to spot Kate. If Anna knew Kathie didn't have any backup she wouldn't be on guard for Kate when the time was right.

Kathie groaned as she held her hand to her head. She saw Anna to her side trying to get up but Kathie quickly grabbed her leg and pulled her back to the ground. "I don't think so".

"Kathie, please tell me that you weren't talking to me! No, forget it I'm calling for backup". Kate got out her phone.

Kathie rolled her eyes but then felt the pain in her leg. She had a shard of glass in her knee. "Crap".

Anna looked at her hands. Not only was her nose bleeding from the breakage from earlier now her hand had glass in it from being pulled down to the ground. "You know I underestimated you". Anna said as they both got up slowly from the pavement.

"Well that's what you get when you mess with a Beckett. Oh and the whole FBI training helps".

That's when Anna's facial expression changed. How the hell did she miss that in her file when she first started looking into Kathie's life a few years ago?

This made Kathie smirk and pull out her gun. "Want to see who can pull the trigger faster?"

Anna took out her gun. "No, no guns...just us".

They both placed their guns down but Kathie was just a little bit faster and got the first shot at Anna. She kneed her in the face, not helping her nose.

Anna was quick to retaliate though, especially since Kathie's one knee was bad. Anna jabbed Kathie in the ribs and then kicked her bad leg, causing Kathie to go down to the ground. Anna smirked and picked up her gun. "Now, we'll see who's the fastest".

Before Anna could pull the trigger a shot was fired and Anna was hit in the shoulder. Not enough to do damage but enough for her to put the gun down and put her hand to her shoulder. Anna turned around and saw Kate standing there.

"Looks like I win". Kate smirked as she made her way closer. Anna knew she had lost and couldn't fight back due the extreme pain in her shoulder. "Anna Walker you are under arrest for murder of Johanna Beckett , Lana Preston, and Victor Pierce, and attempted murder of Kathleen Beckett and Kate Beckett". Kate said as she put the handcuffs on her and read her her rights. She had finally done it. She arrested her mother's killer.

The back up she had called took Anna away as Kate helped her sister up. "You okay?"

"I've been worse". Kathie smiled. "We did it Kate". Kate smiled and nodded as she hugged her sister.

Castle was at the precinct, trying to help Ryan and Esposito with a case, when Gates exited her office with a look they had never seen before...it was happiness. "Guys, you should come and look at this".

They quickly headed into the office where they saw the news on Gate's T.V. The listened to the news castor. "Breaking news, head gang member Anna Walker has just been arrested for the murder of Johanna Beckett, Lana Preston, and most recently Victor Pierce. She is also being charged for the attempted murder of NYPD detective Kate Beckett and Queen's high school teacher Kathleen Beckett, who were both at the scene" That's when everyone's smiles went away. "No word on how their condition is".

No one knew what to say. Their co-worker and their co-worker's sister could be dead or close to dead.

"Call every hospital and see if they've checked in". Gates advised Esposito and Ryan. They quickly exited her office and went to their phones.

Castle couldn't believe this. They had caught her and Kate could finally move on with her life...but she might not be alive to do it. He had to go and try to find them. First stop would be the crime scene.

Kate had taken Kathie back to Kathie's apartment to treat her knee. The glass didn't do much effect for stitches but it would leave a mark for a few days. Kathie was sitting on the sofa with Zeus on her one side and Kate on her other as they hung up the phone. They had just called their father to tell him the good news. They could finally rest.

Kathie looked at Kate. "You know what we should do?"

"Go see mom?" Kathie nodded. "Are you going to be okay?"

"I'll be fine".

They exited Kathie's apartment and got into Kate's car, heading to the cemetery. Once they were at their mother's grave they placed the flowers down by her tomb stone.

"Hey mom, it's your wonderful daughters" Kathie smiled and so did Kate. "We got her".

"You would have been proud to see how brave Kathie was. You really should of taken that FBI job".

"Well then I wouldn't have the award for being the bravest English teacher now would I". She smirked before looking back at the tomb stone. "Kate's going to visit Castle tonight. She's finally going to tell him that she's madly in love with him".

"I am not going to say that exactly".

"No, she's just going to plant one on him and leave him speechless".

"That's impossible to leave him speechless".

"So you've kissed him before that you know that?" Kathie smirked and Kate just gave her a look that said you are lucky you're my sister.

Their mom would be smiling now if they were having this conversation at the kitchen table in dad's cabin, just like she used to when Kathie would tease Kate about the guys she thought were cute and vise versa.

"We hope you're proud mom". Kate said as she placed one of her hands on her tomb stone. "And don't worry, Kathie's knee will be better in a few weeks".

"Not wearing high heels for a week is going to feel so weird".

Kate rolled her eyes. "That's what you're worried about?"

"Why? Should I be worried! Did you not take all the glass out and are using this to have an excuse to stay at my apartment! I knew I should of went to a real doctor".

Kate rolled her eyes at her be so dramatic. "You know you should join Martha's drama school".

Kathie was the one now to roll her eyes. "I bet you I'd be the star of the class" She smiled and so did Kate. Kathie placed her hand on her tomb stone. "We'll come back soon, Mom".

Kathie and Kate headed back to the car and headed back to Kathie's apartment. Before they entered her apartment Kenny came out. "Kathie! Kate! You're alive!"

They gave him a confused look. It wasn't five o clock so the news couldn't of shown their story yet. Plus they asked not to be filmed why exiting the scene. "What are you talking about?"

"The news! They aired your story hours ago that you arrested your mother's killer. Congratulations by the way! But they also said that they had no idea about both of your condition".

The two girls looked at each other and sighed. Whoever heard the news must be worried sick. Kate immediately thought of Castle, Ryan, and Esposito searching all over the city. "Go to Castle's. I'll be fine. If I need anything Kenny is here".

Kenny nodded and Kate gave him a soft smile. "I'll be back soon".
