A/N Hey guys...so this is a Fic I came up with after "Probable Cause" I hope you like it and please review...

It was late. Everyone was almost gone from the precinct, except for Detectives Kate Beckett, Javier Esposito, Kevin Ryan and of course the mystery novelist Richard Castle. It was a hard case and wrapping it up this time wasn't as easy as any other case. A little boy died stabbed in the abdomen, because was defending his friend against some gang in Queens. For Castle it was one of those in which he thought about Alexis and if something would happen to her. He and his partner Detective Beckett saw the pain that mom went through when they delivered the tragic news. He never experienced such a feeling of sadness along with rage against the responsible.

Kate Beckett knew that look on her partner. It was pain and worry. She knew it because it was the same look he gave her when she was shot, and it was the same look when he saw the body of that little boy dead on the ground. She hated that look.

"Hey." she says. She gets no answer, so she tries again a little louder and placing one hand on his lap. "Castle."

"Hmm?" He's barely listening, he just can't get the image of the boy lying on the ground soo cold.

"Go home." She says. "You look exhausted and honestly you don't need to stay and watch me do paperwork."

"I'd rather wait Kate." He says, his voice like a whisper. "I want to stay."

"Look..."Kate says, caressing his cheek with her hand to make him look at her."I know how hard this case was for you, but staying here won't do you any good. You need to go home, take a shower, drink something if you want. I promise you that as soon as I finish here I'll go to your place."

"You promise?" His eyes were pleading, piercing her soul and aching her heart when she saw how bad he was hurting over this case.

"Always."

With that he finally decides to leave without saying goodbye to anyone and goes home, but he doesn't hail a cab. Right now he needed to walk, set his mind right so that when Kate comes to his loft she would have his full love and attention.

After almost 20 minutes walking, about 10 meters ahead from where he was he saw three guys standing by the wall of an empty alley. "That's odd." he thought. He crossed the street, just to be safe not realizing that there was a young blond woman walking almost reaching the alley. He turned his face to the men standing and he saw something shinny, and that's when he put the pieces together. they were gonna robbed her. He immediately crossed the street again watching with horror how the three guys took her. He ran into one of the guys and started fighting throughing, punches, kicks, basically anything he could think of. He wasn't an expert, but he certainly was not gonna let that girl get hurt.

"Run!" He yells."And call the cops!" He manages to throw a punch in the face of one of them but in that moment another comes behind him pushes him against a van parked there. Castle tries to look at the guy in front of him, noticing that he has a star tattoo in his hand. it is impossible to look at their face because the alley has no light whatsoever. Then, everything happens in a blur. One of the guys picks up the knife from the ground and shoves it against him. He immediately feel a blinding pain in his lower abdomen and then a warm liquid pouring down his skin. It was blood. suddenly starting to feel weak, Castle keeps going until the adrenalin wears off, tries to fight the three men at once with all he's got. Is not enough and he knows it.

He doesn't see the third guy until he hears the sound of a gunshot and then he falls to the ground. They shot his leg. Two of the guys pick him up, easier now because he's so weak he can't fight anymore. What Castle didn't realize was that the girl he was defending was now fighting with the third guy until she finally took the gun and another shot rang out.
There was a brief moment in which Castle looked at her. There was fear all over her eyes, but also helplessness. He can't take it anymore, he's starting to feel tired while the two remaining guys take him into the van and his eyes see anything but black.
