Did you miss us!?

Castle was on his West Coast book tour for eleven days and today he was coming home. It was fun hanging out with Mrs. Rodgers, but I'm not going to lie, I missed Castle. I mostly visited my friends and hung out at their house while he was gone. Mike, Leon, and I were having a blast for the past two months. Especially since I got the okay from my doctor that I didn't need to wear my sling any more.

Speaking of two months, I haven't seen Aunt Kate for that long. Sure we Face Time each other and give each other phone calls, but it's not the same. She seems to like her new job though, but she said it was pretty difficult and has a lot of new stuff to get used to.

She's supposed to be visiting us today because we haven't seen her for a while. Castle and Aunt Kate have been canceling on each other lately do to scheduling conflicts. I'm so excited for her to come back. I can't wait to see her. I just don't want her to cancel like they've been doing.

Alexis came back this morning and not alone, she has this new guy in her life named Pi. He's kind of weird, and all I wind up doing is running into their gross make out sessions. And it's only been half a day.

I was knocked out of my thoughts when I heard the door open downstairs and I faintly heard Mrs. Rodgers, talking to Castle. I quickly ran downstairs to see Castle with his cardboard cutout of him.

"Castle!" I said running to him.

"Hey, if it's not mini Beckett. But I guess you're not so mini anymore. Did you grow while I was gone?" Castle asked while giving me a hug.

"Two inches. I'm 4'10" now."

"Wow, I wonder if you'll be as tall as Kate."

"That would be cool. My mama was about 5'7", two inches shorter than Aunt Kate, so I'll still be tall… Maybe."

"Well, I think you will."

"Yeah."

"Now I'm gonna go change. I'll let this guy fill you two in on all the details. He's best with rhetorical questions," he said and then caught a glimpse of Alexis's bags by the stairs, "Is Alexis back?"

"Oh, yeah. She came in this morning," Mrs. Rodgers said.

"I thought she was in Costa Rica until…" Castle started.

"Next week. Surprise!" she said.

"Yeah and she's not alone," I mumbled.

"What now?" Castle said as his eyes went wide.

"Daddy? Hi!" Alexis said as she came down stairs.

"Mmm, come here, you. How was your trip?" he asked as he gave her a hug.

He kept looking over at me, trying to figure out what I meant about not being alone. If I was correct, he'd be finding out really soon.

"Oh! Amazing. Just wait till you see our pictures," she said.

""Our" Picture?" he asked.

"Hey, Al? Where do you keep the matches? I wanna light these sage bundles," Pi said as he came down stairs.

"Surprise!?" I whispered next to Castle.

"Dad, Pi. Pi, Dad," Alexis introduced them.

"Hey Mr. C," Pi said as he gave him a hug, "Awesome to meet you."

""Pie." Like the dessert?" Castle asked.

"Without the E. Like the Greek letter," he said.

"Or like the book and movie, The Life of Pi," I chimed in.

Alexis gave me a look and I just shrugged.

"She's right. But, personally, I feel the whole spelling thing just stifles creativity," Pi said with a smile.

Castle gave Pi a look and said, "The "spelling thing"?"

"Let's let my dad decompress. Matches are in the kitchen," Alexis said, pulling Pi away to the kitchen.

"Okay," Pi said.

"Well at least he didn't bring a tiger, but I admit, it would have been cool," I whispered.

Castle threw a glare my way and I threw my hands up in surrender. I thought it was funny, at least a little. Castle looked over at his mom and said, "He's not staying here?"

"Oh, he is," Mrs. Rodgers said as she was heading towards the front door.

"Not in her room?"

"You get to have that talk. I have a class. Ta-ta."

"So gross," I mumbled, watching the two puppy lovers kissing in the kitchen.

"Uh, Alexis, could I talk to you a second?" Castle said, breaking up the two young lovers.

Alexis came over to us and she said, "Give him a chance, Dad. I really like him, and he's brilliant."

Pi dropped some pots in the kitchen and I just shook my head.

"Found 'em," Pi said showing the matches.

"We'll talk about this later," Castle said.

"Mmm-hmm," she said.

They went upstairs and Castle said, "Uh, make sure you put some blankets out on the couch for Pi if he's staying. I want him to be comfortable. And Visible."

"We have a long road ahead of us Castle," I said.

Castle rolled his eyes at me and answered his ringing phone, "Please tell me your flight is not delayed. I don't think I can bear another minute not seeing you."

"Is it Aunt Kate!? Put it speaker," I said.

He did and I just caught her sentence, "I'm sorry, I'm not at the airport."

"You're not coming, are you?" he asked.

"What?" I said sadly.

"I'm sorry you two. I just got put on a priority case," she said.

"Kate, we haven't seen each other in six weeks," Castle said.

"Trust me, this was not my call. I'm just as upset as you are."

"No, I know. I'm the one who canceled last time."

"I gotta go. I will make this up to you. The both of you. I promise."

"Right. I'm gonna hold you to that."

"Okay, I love you both."

"Love you, too," we said.

"Bye."

"Bye," we said.

He hung up and looked at his cutout, "What are you smiling about?"

"This sucks," I said.

"I know."

"I miss Aunt Kate."

"Yeah, I understand. I miss her too."

Castle got a look on his face and I said, "What's that look for Castle?"

"What look?" he said.

"The, I have a plan, look," I said.

"I was just thinking, if Kate can't come here…"

"We'll go there."

"Not we, just me."

"What!? Come on Castle, I haven't seen her just as long as you have. I want to see her too."

"I know, but I want to be alone with her."

"I can go for a walk or something and give you two some alone time…"

"I don't know, mini Beckett…"

I got on my knees and started pleading to Castle, "Please let me go… I promise I'll behave…I don't want to stay here alone, watching The Life of Pi with Alexis… Please…"

"All right, All right… I hate when you give me that little puppy dog face," he said.

"Yes! I'll go pack," I said running up the stairs.

We were in D.C. and it was an awesome place. I couldn't believe all of the buildings, especially they lit up at night. This was my first time here and it's pretty sweet. We got to Aunt Kates apartment before she did and decided to surprise her. She was starting to undress in her bathroom mirror and Castle am out of the shadows, frightening aunt Kate, making her pull her gun on him.

"Oh, Can you at least finish taking that off before you shoot me?" he said.

"Ew… I am here, you know?" I said coming out from behind him.

"Castle? Em? Uh, what are you doing here?" she asked.

"I know I promised to respect your job, but I couldn't go another week without seeing you," he said.

"Same here, I wanted to see you too," I said.

"You shouldn't have come here," she said.

"So you want me to leave?" he asked.

"Oh, immediately," she said.

They kissed passionately and I said, "Do you want me to give you two some time to catch up?"

Kate looked awkwardly at me and said, "Sorry, I forgot you were here."

"It's cool. You two love birds missed each other."

She rolled her eyes and she pulled me towards her for a warm embrace.

"I missed you, Em," she said.

"I missed you too," I said.

"Did you get taller?" she asked.

"Yep, I'm 4'10" now."

"Wow, I'm gone two months and you start to grow. How's your elbow?"

"Fine, I got my sling off about a week ago."

"I'm glad you're okay."

"It was nothing."

"I'm glad you're both here, though."

"Yeah, me too. This is great," Castle said.

"Yeah," I said.

I slept on the small love seat my aunt had while they took the bedroom. In the early morning hours, I heard Aunt Kate sneak out into the main room. She sat at her dining table and I figured she was working on her case, so I let her be.

A few hours later Castle came out and said, "Hey. How long have you been up?"

"Couple of hours. I had some homework to do," she said.

"Maybe we should do some homework, too."

"Still here," I called out from the love seat.

"Not supposed to get those innuendos…"

"I lived in a bad neighborhood… You're going to have to try harder."

"Okay, you two. To answer your question Castle, I would love to, except I'm still proving myself. I got to know these reports better than the people that wrote them," Aunt Kate said.

"Is this your case?" he asked.

"Yeah."

"What's it about?"

"Castle. It's classified."

"You do realize that only makes me more curious. So is it big?"

"You know I can't talk about it."

"Doesn't mean I can't guess. It must be big. You had to cancel our weekend together. Must be local, because you're still here. I bet I can figure this out."

"Well, that doesn't mean that you should."

"Come on. Don't you miss working together?"

"Yes, I do."

"So if I were to help you, maybe we could solve whatever this is faster, and then have the whole weekend to ourselves. Wouldn't you like that?"

"I would. Until I got arrested for disclosing classified information."

"Oh, Come on. Who's gonna know?"

There was a knock on the door and I lifted a brow from where I was sitting on the love seat.

"Wow. They're good," Castle said.

"I've gotta go. That's my partner," Aunt Kate said.

She got up and dropped her folder, "Oh. Sorry. No, no. I got it."

"I'm not looking. So what time will you be back?" he asked.

"You know what? I'm not quite sure. I'll give you a call as soon as I find out," there was a knock on the door again and Aunt Kate opened it, "Hey, come on in."

"Hey, are you ready?" a lady asked as she walked in.

"Uh, yeah. I just gotta get my bag," my aunt said.

"Your fiancé's visiting."

"You're Agent Mulder…" I said as I walked over to the lady.

Castle huffed out a laugh and the lady said, "It's McCord."

"Yes, my niece and fiancé are visiting. Except they know that we're working. Guys, this is Rachel McCord. She's my new partner."

Castle shook her hand and said, "So, you're the new partner."

"Yep," she said while giving him a stare down.

He just smiled at her and I stood next to them, watching the strange interaction going down. The lady looked more like a doctor than an agent, but I guess they're both tough and great jobs to have.

"Chiefs waiting. Gotta go," Agent McCord said.

"Yeah," Aunt Kate said as she ran out of her room.

"Bye," Castle said.

"Bye," Aunt Kate said.

"Bye Agent Mulder and Agent Scully," I said.

Aunt Kate rolled her eyes at me and placed a kiss on my head. She clicked her tongue with a wink at Castle and left quickly.

"Have fun saving the… World," Castle said.

"Well, her new partner seems… Nice," I said.

"The X-files? Really?"

"What? They're FBI agents, I had too. Not a fan?"

"It was okay."

"What, did you like more of the short lived Sci-fi series?"

Castle rolled his eyes and looked over at the dining table. He walked over and grabbed a glossy photo which most likely fell out of Aunt Kate's folder.

"Oh, you forgot you're…" Castle said as he looked at the photograph.

"Castle, you're not going to butt into the case, are you?" I asked.

"I… Well, you know… It could be fun."

"We're going to be so dead. And not to mention thrown in jail for looking at confidential information."

"It'll be fine. We won't get caught."

"You know how many times we've said that."

"Trust me."

"We're done for…"

Castle started researching the numbers from the picture and decided to call Ryan and Esposito for help. I was still reluctant about this whole thing, but I got to admit, looking into a federal case was kind of exciting.

"Esposito," Esposito said as his voice ran through the phone.

"'Sito! It's me," Castle said.

"And me," I said.

"Castle? Emily? I'll put you on speaker," he said, "So where you been, bro? You've missed, like, three Halo nights."

"I told you, I was on a book tour," Castle said.

"Yeah? Did you tell your book groupies you're engaged now?" Ryan said in the back ground.

"You're swaddling that doll right now, aren't you?" Castle said.

I snickered at his statement.

"So listen, we just finished a case. Come have a drink with us after work," Esposito said.

"Oh, I'd love to, but I'm working on a case of my own right now. For my next book," Castle said.

"Oh, so you just called us 'cause you need some expert technical consulting?" Esposito said.

"Well, since you offered, I'm writing a scene about someone trying to investigate a crime using only one evidence photo, a crime involving national security."

"So your hero's a spy?" Ryan asked.

"More like a ruggedly handsome everyman. Anyway, the photo is of a blown transformer, so I pulled a random photo of a transformer off the Internet, and there's a serial number on the side. I'm trying to determine how much my character could figure out just from that number. I'm wondering if my character's police buddies might have any resources," Castle said.

"Well, if your hero's fictional cop buddies are anything like your real cop buddies, then they'd have real work to get back to, so, Bye-bye now," Esposito said.

"What if our hero was offering Knicks floor seats?"

That sure got their attention and Esposito said, "What's that serial number?"

"Here, A-P-5-7-3-9-2-1-5," Castle said.

Ryan and Esposito went to their tech girl and she said, "Here we go. The "AP" stands for Allegra Power. They service Northern Virginia."

"And would it be possible to trace the location of that transformer using that number?" Castle asked.

"Yeah, sure. The transformer with that serial number controls a 10-square block region of the Ashton Heights neighborhood in Arlington," she said.

"Thanks, you guys. You saved the story."

"Whoa. Guys, that exact transformer was sabotaged two nights ago. And the Feds are investigating."

"Arlington? Isn't that Beckett's backyard?" Ryan asked.

"Castle, is this a real case?" Esposito asked.

"Well, actually, I… what? Tunnel…call…later…when…I…b," Castle said as he promptly hung up.

"Not gonna get caught," I said.

"They don't… They don't know," he shrugged.

"Yeah…"

"All right, why would someone blow up a transformer?" Castle asked.

"Terrorism?" I asked.

"No, that would've been in the news. To cause a blackout?"

"How does a black out affect national security?" I asked.

"Hmm… Not quite sure."

"But I have a feeling we're going to find out."

"Yep, you up for a trip to the power facility?"

"We're going to be in a federal prison for the rest of our lives."

"We'll be fine. We won't get caught."

Castle figured out that across from the power plant, there's a golf course. He thought about another case where the suspect used the drainage system to escape, which would be the perfect place for this case. Especially since it's on a federal level, they wouldn't want to be seen by any cameras.

We were riding around in a golf cart, driven by a security guard, who worked at the golf course by the plant. We already spoken to a few other ones at the course, but so far we haven't found out much information. The security guard stopped and we got out, to face to face with Aunt Kate and Agent McCord.

"Agent Beckett. Agent McCord. What are you guys doing here?" Castle asked.

"What are you guys doing here?" agent McCord asked.

"Well, I figured since, uh, Beckett was working, we'd just get in a few rounds."

"Where are your clubs?"

"Crap."

"Nice going Castle," I said.

"Do you realize what would happen if I told the chief that he was here? You would be kicked off the team, not to mention obstruction charges against you. This is my one and only warning. The next time I see you, it'd better be on a book jacket," Agent McCord said and walked away.

"Wow. Okay, she is not invited to the wedding," Castle said.

""Get in a few rounds"?" my aunt asked.

"What did you want me to say? That you accidentally left out your evidence photo of the blown transformer?"

"Castle, you went through my classified photos? What the hell were you doing?"

"Trying to help. I didn't think I'd get caught."

"I told you we would," I said.

"Quiet you… Well, you did Castle," my aunt said.

"Yeah," Castle

"How'd you get here, anyway? I mean, why are you here?"

"Well, the transformer led me to a research park where all the tenants have government contracts. I figured maybe they're using the blackout to circumvent the security system, but they're not just gonna waltz in through the front door. Then I remembered that case we had at The Old Haunt, where the killer used…"

"Used the abandoned sewer tunnels underneath New York, yes."

"You thought of it, too!"

"Except this isn't New York. Do you realize how many laws were broken by looking at that photo? Are you trying to get me fired?"

"Would make it easier to see you."

"True," I said.

"Not if I was in jail!" she said.

"Right," he said.

"Look, I wanna see you, too. But it can't be like this, okay? You have to promise you're gonna stop fiddling with this investigation. The both of you."

"Okay, yeah. I promise."

"Me too," I said.

"But wouldn't you at least like to hear what I found out?" Castle asked.

Aunt Kate shrugged with a soft mutter, making sure to keep an eye out for her partner.

"Right. These guys didn't see anything the night of the blackout. It was too dark. But that guard over there remembers seeing a guy a couple days ago in a late '90s model gold Sedan. He was probably doing some kind of recon."

"Castle."

"If you have them send over their surveillance footage…"

"Castle. Castle, Please?"

"Right. Sorry, okay, I'm out."

"Good."

"I promise, wiped from my brain. It's like I wasn't even here."

"Thank you," she whispered and then waved bye, "I gotta go."

"Of course," Castle whispered.

She left and I said, "Nice work Castle."

"You just… You…" Castle said as he started walking away.

I chuckled as I shook my head, following after Castle, awaiting our next failed adventure.

Castle dropped me off at Aunt Kate's apartment and he went out to the store, to buy some food to cook. He wants to make it up to Aunt Kate for getting involved with her case. It was taking him awfully long and I wondered what was up.

I decided to call Aunt Kate and ask her what was going on.

"Em, you okay?" I heard my aunt ask.

"Yeah, have you heard from Castle?"

"Yeah, we're holding him in interrogation."

"Wait, what!? Why?"

"He was in the car with a guy we were looking for. Turns out he was abducted by him."

"Oh… Wow…"

"Yeah… You sure you're okay?"

"Yeah, but will you guys be done before dinner."

"Em…"

"That's a serious question."

"I don't know. Just sit tight and stay alert."

"Will do Agent Beckett."

"Emily…"

"Bye…" I said, hanging up.

I can't believe Castle was abducted by the man they were looking for. Of all the luck, right? At least I wasn't there. It think I've had my fair share of kidnappings. At least he's okay though, but I really hope they're done soon. I'm hungry.

We were sent home the next day and I had to say goodbye to Aunt Kate. Even though I only saw her a little bit, it was still a nice reunion. As soon as we walked through the door, Pi greeted us, "Mr. C! Mini B! Qué pasa?"

"Pi," we said.

We walked in and over to where Pi was making dinner and Castle said, "Where's Alexis?"

"She went shopping with her grandma. I volunteered to make dinner tonight, and I'm just getting a jump on the prep. Can I count you guys in on a nice, juicy steak?" he asked.

"These aren't Steak?"

"That's papaya steak. It's the juiciest steak there is."

I looked at the fruit and made a disgusted face. Well, this is going to be an interesting roommate.

"This is all fruit," Castle said looking around the kitchen counter.

"I'm a fruitarian," Pi said.

"Of course you are," Castle mumbled.

"It's all that I eat. Original diet of mankind. Nutrition as God intended."

Castle picked up a banana peel from the floor and tossed it, "You know, Pi, don't, uh, take this the wrong way, but how long do you plan on staying at casa de Castle?"

"You know, I'm actually in a little bit of a bind. See, I live in Amsterdam, but I, uh, kinda lost my passport. But, hey, you don't wanna hear about my troubles. You got your own, right?"

"I do now. You are gonna clean all this up?"

"Mr. C., I get the feeling things didn't go too well in D.C. with your fiancée, did they?"

"No, Pi. They did not."

"You know, sometimes the best thing to do is talk about it."

"You know what? You're absolutely right."

"Where you goin'?"

"I'm going to find someone to talk about it with."

I followed Castle to the door and he said, "Stay here."

"Don't leave me here with fruit boy," I said.

"Just keep an eye on him for me."

"Fine…"

Castle left and I looked over at Pi who gave me a giant smile. Well, this is going to be fun.

My time alone with Pi was actually kind of fun. Don't judge a guy until you know the guy, right? He actually taught me a few things I didn't know and his papaya steak is actually pretty tasty. He let me taste some before dinner. Pi is really a cool guy and I see why Alexis likes him so much.

Alexis and Mrs. Rodgers came back a little while ago and Alexis helped Pi with the rest of the food. Castle came back a little after them and went straight to his office. I wondered what he was up to. Hopefully it wasn't about Aunt Kate's case, or he'll get in even more trouble.

Alexis went to get Castle for dinner and I watched Pi put on the finishing touches to the dish. There was a knock on the door and wondered who it was.

"I'll get it," Mrs. Rodgers said.

Mrs. Rodgers opened the door and in came two men in suits. This did not look good. I followed them into Castle's office and hi mom said, "Richard, these men are here for you. They say they're federal agents."

"Mr. Castle, you need to come with us right away," One agent said.

"What is this about?" Castle asked.

"Please sir. Just come with us."

"Why?"

"You too, little one," the other agent said as he grabbed my arm.

"Me?" I asked.

"Wait a minute, you can't just take them away…" Mrs. Rodgers said.

"Just do me a favor, call up my lawyer. And call Beckett," Castle said.

"Dad, this… Dad!" Alexis called out.

We made our way to D.C. and I wondered what was going on. Were we really in serious trouble? I blame Castle for all of this. We were brought into the place Aunt Beckett worked with the FBI and we had our blood drawn.

"I blame you Castle," I said as we sat in the interrogation room together.

"Why?" he asked looking shocked.

"You got me into this."

"I didn't…"

"Yeah, you did. You made me look at the photo and go to the power plant."

"I didn't make you."

"Okay, fine, but still."

"They aren't going to throw an eleven year old in prison anyway."

"Yeah, I guess."

It was silent and then Aunt Kate came in.

"Beckett. Finally. What's going on? Why won't anyone talk to me? And why would they take our blood?" Castle asked.

"Castle, you know that case that I've been investigating, the break-in and the theft? Well, it turns out there's more to it than we thought," she said as she brought a seat up to Castle.

"Are you gonna waterboard me? Because that would seriously affect our relationship."

"No, babe, can you listen for a second? Um. It turns out that something else was stolen from another lab in that building. It was a chemical agent that they were working on for the military, but it was deemed too dangerous to use. The amount stolen was enough to kill thousands of people."

"Isn't this "need-to-know" stuff? Why are you telling me?"

"Because that toxin was used to kill Jack Bronson, the man that abducted you. It was aerosolized. It was placed in the ventilation system of his car."

"I was in that car."

"How do I fit in to the equation?" I asked.

"You were just a precaution," she said.

I nodded, but this was not looking good for Castle.

"Was I… How bad?" Castle asked

"Based on the amount found in your bloodstream, you have less than a day to live."

That sentence broke my heart. Was Castle seriously going to die…?
