A/N: Gina still showed up right before Detective Kate Beckett was about to tell writer Richard Castle how she felt. Castle still disappeared for the summer thinking Beckett was falling in love with Tom Demming. Beckett still walked into a crime scene only to find Castle standing over a dead body holding a gun. Castle still was the person Beckett went to when Raglan contacted her about her mother's case. Castle and Beckett still almost died in each other's arms in the freezer. They still faced death hand in hand before Castle pulled the wires out of the dirty bomb saving not only them, but an entire city. Josh still showed up right before Castle was going to tell Beckett he wanted more. Montgomery still died in the hanger giving himself up to keep Lockwood from getting to Kate Beckett. And the sniper still showed up at the funeral to try and put Beckett in the ground once and for all. The only difference… Richard Castle reacted just a little bit faster.
Having to carry Beckett out of that hanger as she squirmed and twisted in his arms trying to break free, begging him to let her go back, begging him to let her stop Captain Montgomery from giving his life to protect her was one of the hardest, yet one of the easiest decisions he has ever made.
When Montgomery called him earlier that evening and told him what he needed him to do, this isn't what he expected. He would never suspect that Roy Montgomery was at the center of what caused Beckett so much pain. He also never expected that he would have to be the bad guy and physically remove Becket from the hanger as she begged him to let her go back to the man who caused the death of her mother. He would have never guessed he had to do the hardest thing he has ever had to do knowing he was carrying her away from a dead man.
But when Montgomery told him that he needed to get Beckett out of there before they saw her, when Montgomery told him that he was doing this to stop them from killing Kate, it was the easiest decision he has ever made picking her up and carrying her out of there because as much as it killed him to see her in such anguish, he knew it would kill him more if anything ever happened to her. He would rather have her hate him and be alive than dead on the floor of the hanger because if there was one thing Richard Castle knew it was that he couldn't live in a world where Kate Beckett was no longer alive.
As he stood there, in the cemetery, he looked around at all the people Montgomery has touched over his lifetime. All of them were left with good memories, they were left believing that Captain Roy Montgomery died a hero. There were only four people who knew the truth. Himself, Detective Javier Esposito, Detective Kevin Ryan and Detective Kate Beckett.
He found his eyes shifting back to her as she stood at the podium, filling the otherwise silent air with words commemorating her Captain. Their Captain. Standing there staring at her as she spoke of Montgomery and how he taught her there were no victories. There were only battles and if you were lucky enough you would not only find a place to make a stand but you would find someone to make a stand with you.
When she looked at him as she said this that is when he decided. He would always be there for her. He would always stand beside her no matter how stubborn she was, no matter how hard she tried to push him away. He would dig in his heals and make a stand and break down her walls one brick at a time because she was looking at him. Not her father, not Lanie or Esposito or Ryan. Definitely not her boyfriend, Josh, who once again was absent when his girlfriend needed him most. She was looking at him because she wanted him to be the person to be there with her as she made a stand. So he made himself a promise. No matter what happened, no matter how hard she tried to put up walls to keep him out, no matter how hard she tried to push him away. He wasn't going to let her go. He was going to be there for her and keep her safe.
And that is exactly what he did as he jumped moments after seeing a glint in the distance.
