Disclaimer : Castle is not mine.

I'm finished. I've written my letters I've done my drawings and it all suddenly feels very real.

Open when... Is written on the front, and I'm in the elevator on the way up to the homicide floor the envelope hugged tightly to me. I get off the elevator and see everyone is around the whiteboard. When I say everyone I mean everyone the captain, dad, Kate, Esposito, Kevin, hell even Lanie and I wonder why she's there as I walk towards them. Deep breath in, deep breath out. I tell myself as I walk closer and closer.

Kate sees me and there's that look of worry and concern. I regret having to do this now but I can't waste no more time. I have no more time and I'm terrified.

Suddenly everyone is looking at me and I can't look them in the eyes. I step right up to Kate I hold out the envelope face down so nobody sees what I've written on the front. She takes it and turns it over which was a mistake I personally think because now everyone saw it and the looks are heartbreaking I turn to leave but I'm stopped by a hand on my shoulder and I turn to look at my dad. He's scared, you can tell his eyes aren't shinning like they usually do.

"Alexis" He says on a breath.

I turn and pull him into a hug trying to hold back my tears, I can see everyone over my dad's shoulder and I turn my head so I can whisper "Listen to Kate dad. I'll understand daddy but I need y you to do the same. I love you daddy."

Castle felt like that sounded like a goodbye. Why was his baby saying goodbye ?

I turn and start walking away. It feels like a goodbye. I want to turn around and take one last look but I can't I know I can't. I turn around as the elevator doors closed. They've all gathered at the end of the hallway where the elevator is. They're all staring at me. The doors are closing and it's then in that moment when I let go and let the tears fall. I can see the pain in my dad's eyes and I can't take it I lean back and I'm sobbing. I'm grateful for the 30 seconds I get to break down in the elevator but by the time the elevator stops and the doors are opening I'm on my feet eyes dry and a smile on my face.

I have a startling realization.

Tonight is the night.

I stand there thinking before I step onto the busy new york streets.

Then I say a silent apology.

I'm sorry to leave daddy.

Then I'm gone.
