Disclaimer: Castle does not belong to me. The characters of Castle don't belong to me. The wonderful Mr. Marlowe and CO are in charge in that area, so I'll just leave it to them.

A/N: I had this idea to have Castle write letters to Kate, to write out his feelings, his thoughts, or whatever he darn wants. He's a writer, so he's allowed artistic freedom.

This is for Joelle because I love her.

My darling Kate,

I'm writing to you even though you'll probably never read this. Maybe you will, once we're together. Then again, maybe not. Only time will tell.

Anyway, I'm writing to you to tell you how beautiful you really are. You truly are stunning. You leave me breathless. Your eyes sparkle, your eyes crinkle when you smile, your laugh sounds like magical fairies singing. You glow. You're radiant. You're indescribable.

I could sit here for hours to wite down every single cliche about being in love that I can think of, but I won't. That's not the point of this letter. I wanted to tell you that you did the most adorable thing today. While we were driving back from the crime scene to the Precinct, you giggled. You actually giggled. You don't really strike me as the giggling type, so I was in awe of what it sounded like. And the other thing is, you were giggling because of something I said. You were giggling because of me. That's what really surprised me. When I first started shadowing you, if I had said what I did right then, you would have hit me, or squeezed my ear until it turned purple; instead, you giggled. We've come such a long way, there's really no question.

I'm really glad that we're as close as we are now. For almost a year now, we've slowly been getting closer and closer, and after we were cuffed together, we've pretty much just been clinging to each other. We're so in synch. Every movement, every blink, every breath matches the other's perfectly. Every nod, every smile, every laugh, every frown, every single thing is in sych with the other.

This letter is just a jumble of words, commas and periods, but that's what my brain is too, so I guess it's okay. All the ideas are mixed up and nothing makes sense, but I guess that I can blame it on love. Love makes people do crazy things. Love is blind. Love is magical and wonderful and painful and beautiful and weird and twisted. Love is irrational. Love is unconditional and unstoppable and it makes you feel like you're floating and it's dangerous and it makes you feel vulnerable and exposed and every other feeling in the world. You get your heart broken. You feel all warm and fuzzy inside. All the songs make sense. There's one thing I'm wondering, though. If love is blind, then how come I can see you so clearly? That's something I've never understood.

So, I'm getting incredibly off track, and I don't even remember what the point of this letter was supposed to be, so it would probably be best if I end it here.

I love you. I will forever and always.

R.C.

So? Like it? Only tolerating it? Have any ideas for the next letter to Kate? :)
