The building no longer existed. There was only rubble and dust. An infinite noice of sirens, people screaming and people crying added to the chaos outside of what used to be the office building, where Black Pawn was located. Police, Fire Fighters, Search and Rescue, Paramedic, where already working, helping as much as they could...trying their absolute best to get as much people alive as humanly possible. None of them knew that the fiancé of a certain detective was buried under mountains of concrete and debris.

It was a slow day at the 12th Precinct. There were no active cases at the moment and Detectives Beckett, Ryan and Esposito were looking forward to a day of paperwork. Not even Castle was there to lighten the mood and to bring Beckett coffee, because he was in a never ending meeting with his publisher and editors about the his new novel. Seeing absolutely no progress on her reports, Beckett stood and went to the break room to make herself a cup of coffee. That's when her phone rang and Castle's picture appeared on her screen. She didn't see the breaking news on the TV, about a bomb exploding in the offices of Black Pawn.

"Hey Castle, how your meeting going?" Beckett asked, though she heard no response. Instead, there was a weird sound. Like a low cough, muffled by the statics of the signal. "Castle where are you, the signal is not very good." Again she was met by some kind of coughing in the background.

"Kate." Her face immediately changed. His voice sounded hoarse and weak. She leaned against the counter.

"What's wrong? Where are you?" Beckett asked, her voice grew more serious.

"Kate listen..." Castle whispered. Beckett could hear his hard breathing against the phone. "Something happened..." More coughing. "I don't know exactly what but..."

"Castle what happened?" Beckett asked once more. She heard metallic sounds in the background.

"I need..." His voice died and a cold ran through her spine. "I need you to go into my safe-box and pull a brown file...can you do that for me, please?" God he sounded bad...sick.

"Castle, please explain to me what's this about." But instead of answeres Beckett was received by more coughing. In that moment Ryan and Esposito walked in with solemn expressions on their faces.

"Beckett..." Ryan said looking down. "You should come."

"Wait...Castle tell me what's wrong please..." She pleaded as she headed towards the TV. She gasped as she saw what used to be a building, immediately understanding everything. "Castle please tell me you're not in there." Her eyes were shining as she watched the news.

"Kate..." Castle's voice was barely a whisper now...like he was dying...no...he couldn't be dying.

"No..." She breathed. Beckett felt tears building up as Esposito put one hand on her shoulder.

"Kate." Castle repeated, this time a little stronger. "It's okay."

"No." Beckett grabbed her coat and car keys. "I'm on my way Castle, just hold on and don't hang up...I'll get you out." Something stopped her. The boys and Gates.

"No Kate, listen to me." Castle sighed. "I...I know you wanna come and help but...look the situation is...bad and...I just don't want you to..."

"What?!" Beckett sat in her chair and ran a hand through her hair. "You don't want me to see it? Too late Rick, it's all over the news! So don't tell me to stay here at the precint and do nothing to save you." Her voice was shaking.

"Is not that simple Kate." Castle said clearly. "I...I can't get out..." Castle heard a small cry from Beckett. "I'm sorry Kate."

"Please don't..." It was getting harder for Beckett not to fight the tears. "You can't say goodbye."

"I'm trying babe...I'm trying so hard not to give up." Castle said resolutely. "But if this is the last time I'm gonna hear your voice...I'm gonna talk to you..."

"Is not."

"I need you to know how much I love you." His voice cracked. "How much I wished this wasn't happening so that I could see you at home tonight...kiss you..." His voice died and was replaced with coughs and debris moving.

"Castle!" Beckett said scared.

"You changed my life Kate Beckett." Castle said weakly. "And for that I can't thank you enough...You're so strong Kate...so remarkable...maddening...challenging...frustating. ..and I wouldn't change it for anything...I love you just as much as I love Alexis and my mother..."

"Castle..." No response. "Rick!"

"Yeah?" He breathed. He wasn't gonna hold on much longer.

"I love you." She sobbed. "I'm sorry...I'm so sorry Rick..."

"It's okay...there's nothing we can do right now." She knew her fiancé was trying to be strong, but it was easy to tell that he no longer had strength to hold on much more.

"I can't believe this is it." Beckett said accepting the fact that the love of her life was gonna die.

"Me too..."

"I'm gonna miss my morning coffee." Beckett heard Castle's weak chuckle. "I'm gonna miss you so much."

"This is not a goodbye Kate." Castle said with the last of his strength. "I'll see you later Kate...just not in this world." He smiled. But before he could say anything else a loud noice echoed on Beckett's phone.

"Castle?" He didn't answer, but she heard more noices. Like something was moving. "Rick?" Nothing. In the distance she heard:

"Guys! I found someone!"

With that, the line went dead.

A/N: Please don't kill me for leaving it like that...I just really need to get my paper done...I may do a sequel though...I hope you liked it
