When Castle entered the precinct he didn't know what was going to happen. After he left to go to the Hamptons without Kate she seemed very upset and now that he was walking in without anyone knowing so, he was bound to get the coffee in his hand moved to all over his face. He was worried she wouldn't want to see him. Was he perpetrating? Was he about to walk onto death's door? The elevators doors opened. Castle smiled and looked up only to see Kate, his Kate macking on someone. He instantly stopped in his tracks and thought about turning around. Instead he forced a cough and looked around. Kate and her friend broke apart fast. Kate and Castle's eye met and she could see a flash of pain pass through his eyes while he saw what he thought was remorse only a little flicker.

"Hey Beckett, I brought you your usual." Castle muttered under his breath and forced it in her hand. He walked around to go say hello to Espo. and Ryan.

"Hey guys! Man did I miss you!" he shook hands with both guys.

"Hey Castle!" They both enthused "Man Beckett isn't happy with you,"

"I noticed. Who, pray tell, is the new boytoy?"

"His name is Josh she picked up a few after you left. Dude you messed her up."

"I messed her up? She didn't want to go that messed me up! I am in love with her guys!"

"In as in still? After seeing that?"

"Yes I'll always love her no matter how much pain she causes me."

"Well bro, I'm glad to hear that but look at her. She's happy,"

"yeah happy to hurt me like that," castle muttered, then speaking to the guys "I see that I hope that she just sees that I love her and hat only bad will come out of what she's doing over there." Castle looked at Beckett and as soon as he finished the statement. The second they made eyecontact again the man grabbed her face and started yelling at her. Very loudly. Kate just stood there and took it. Castle couldn't stand it a second longer. He paced over as well-mannered as he could, grabbed the man's arm and took it off of Kate's face.

"Don't. Ever. Touch. Her. Again." The man went to interrupt Castle. "Understood?"

"Why do you care? Writer Boy"

"Maybe because I love her? And it sure the hell doesn't look good when your yelling and grabbing a police officer IN a police station."

"We'll finish this when we get home Kate."

"Oh no, I don't think your understanding me. You come near her, touch her, call her, talk to her, stalk her, I don't even want you looking at her when you pass her on the street."

"Kate,"

"What did I just say" Castle said putting pressure on his elbow threating to break it. "Leave. Kate. Alone." He repeated through clenched teeth.

"Alright!" Josh yanked his arm out of Castle's grasp and took his leave but, not until hitting Kate as hard as he could and spitting in Castle's face.

"Ohmigod Kate are you okay?" Castle kneeled down to where she fell and cupped her face in his hand. She reached up in her long sleeve shirt and wiped the spit off his face.

"Castle thank you." She wrapped her arms around his neck and held him close. She didn't let go even as they stood.

"Common Kate, Lets get you home."

"Castle he'll bethere when we I get home. I don't want to go."

"Then you'll come home with me.
