They were seated in the Ferris wheel when in started to move.
"So I uh I think I should err explain today then." When Beckett just starred at him he continued "When I was about 17 I was in the army, I struggled a lot and my mother agreed to sign the forms, kids picked on me and we both thought it would be good for me and it was it was the best thing for me, when I came home for a month that's when I met Meredith and you know what happens from there. I was about 25 at the time when I received a letter from her telling me everything how she was pregnant and how she needs me home, but I couldn't I still had another 10 months before I could go home again." He took a deep breath "I was a few months away from going home and Meredith would have just turned 9 months pregnant but I was injured, shoulder damage and I was sent home. I had the option to continue because I have been serving for almost 10 years. I chose Alexis and marrying Meredith was never my idea, I ha already started writing a few years before that and saved a few things and that's when I sent all the things I had written to publishers all over New York and within a year Alexis was 1 and Meredith was cheating on me and we were living in this tiny apartment and that's when Black Pawn contacted me and naturally Meredith became interested but I said no got a divorce full custody and a new apartment."
"Castle what has this got to do with today ?" Beckett asked fearing his response.
"I got a letter last night delivered to my door by an official military personal and they've called me back in for duty and I wish I didn't have to go but I have to. I don't want to leave Alexis, mother and you guys, especially you and I'm scared Beckett it's a scary place to be especially when you have a family here."
"When Rick ?" She had tears in her eyes.
"I ship out in a few days they're picking me up from the precinct, they knew about my arrangement with the 12th and are giving me an opportunity to say by."
"How long ?"
"I don't know but I'm gonna write to you I promise Beckett, I'll write a letter for each day of the week and I will send them without fail."
"Castle." She was openly crying now. She didn't mind that he never told her about this she cared more that he was leaving and she wanted to tell him so many things and she had so little time and she didn't know when she would see him again.
"Does your family know ?"
"Yeah I uh told them yesterday. You should have seen Alexis' face Beckett she cried so much and I couldn't do anything but hug her and tell her I would try my hardest to come home and she just cried and I cried and Mother was crying. Me and Mother knew there was a possibility of this happening."
"Spend the night at mine, we can have a sleepover and create knew memories and talk and eat junk food and-" She's crying and the tears won't stop running down her cheeks.
"I know Beckett I know but we're going to need to go back to mine, I need to spend as much time with my family as possible."
"Of course."
They reached the top of the Ferris wheel and Beckett grabs his face and whispers "Kiss me Castle." And then she's kissing him, soft and gentle but also fierce with her feeling towards him and so many things unsaid.
When they pulled apart he looked into her eyes "I will come back Beckett. I'll come back for you. For us."
