A/N: Here it is, the last chapter. I cried writing this. SO MUCH. Please leave a review of the story or whatever. I would like to hear your feedback. I'll be starting another story in the near future, so watch out for that :)

A little over a month had passed since Brian and Olivia had renewed their vows. They had been spending as much time as they possibly could together. They both knew Olivia didn't have much time left. It scared them both to about it.

Brian and Olivia were cuddling on the couch. They had been watching some movies they loved. Olivia had soon fallen asleep. She could barely stay awake anymore.

Olivia had told Brian about when she had thrown up all over the place. That had scared Brian. It had happened twice since that day. Both times resulted in Olivia being rushed to the hospital. The doctor had tried to tell them in the nicest way possible that this meant the cancer was very bad. Of course, Olivia already knew that.

Brian gently rubbed Olivia's arm as she slept. He knew she was in pain all the time now. It upset him to know that she was. He wished he could help her, but in actuality all he could do was try to make her as comfortable as possible.

Later that night, Brian had carried Olivia into their bedroom. He laid her on the bed and adjusted her oxygen tank. Once everything was set he crawled into the bed and soon fell asleep.

In the middle of the night Brian woke up to Olivia crying.

"Liv, what's wrong?"

"I am in so much pain, Brian. It is getting harder to breathe." Olivia sobbed and began gasping for air.

"Olivia, just calm down. Just stay calm okay? I am going to call for help."

Olivia shook her head. "No Brian. I don't want to die in the hospital."

Brian's eyes instantly filled with tears. She feels like she is dying right now.

"Just let me call your Captain. He will want to see you."

Olivia nodded and cried out. She knew she was dying. She was in so much pain.

A half an hour later Fin and Cragen walked in. Olivia was half asleep half awake.

"Hey babygirl. We are right here." Fin kneeled on the floor beside where Olivia was lying.

Brian sat on the bed next to Olivia, holding her in his arms. She was so weak and in pain. Brian's tears never stopped.

Olivia gasped again and cried out.

She looked at Cragen with her weak eyes. The fire that was usually in Olivia's eyes was burning out. Cragen could see it. Tears flowed down Cragen's cheeks. This was it. Olivia was dying right in front of him. The woman who saved countless lives was losing hers. The world would never be the same.

"Captain." Olivia's voice was a whisper. She could hardly speak.

"What is it Liv?"

"Thank you for teaching me so much all these years. I am grateful for that. Now listen, when you go to work on Monday, I don't want my desk decorated as a tribute to me. I don't want that. I want you guys to do what you normally do. There are people who need saving and you guys can't slack off. You tell the others I said this. No slacking off. Ask them this, what would Olivia do?"

Cragen chuckled through his tears. The Olivia he knew was still there.

"Olivia you are strong. I will miss you so so much."

Olivia nodded. "Me too."

"Fin. You keep Amaro and Rollins in line. I haven't worked with you guys for a year, but I know what Amaro is like after something bad happens to someone he knows. Don't let him get himself into trouble. And keep Amanda in line too. She has her moments. Fin, I love you like a brother. Please move on. Don't stay in the past and mourn. Go and live your life. I didn't do that and I regret it so much now. Find you happiness Fin."

"Got it babygirl." Fin held Olivia's hand in his and kissed it.

Olivia felt another pain and groaned. Brian kissed her cheek and whispered into her ear that it was okay, that she could let go now.

Olivia looked up at Brian. "I'm going to miss you." She couldn't stop her tears. Her she was, dying in her own home and saying goodbye to her husband, her co-worker and her boss. She loved them all.

"I love you, Liv. Never forget that." Brian held her tighter. Part of him didn't want her to let go. He knew she is in intense pain. He wanted her to let go and be pain free.

"Brian, I love you so much. I always will. I will always be with you. Remember that."

Brian nodded as Olivia fought to keep her eyes open. He knew she was scared that if she closed them she would never open them again. He was scared of that possibility too.

Olivia Cassidy died on September 5th at 3:07 am. She died in her husband's arms and was surrounded by the three people that she loved the most.

It was the day of Olivia's funeral. Brian was in his uniform, sitting in the back of the church. He had not stopped crying since he saw Olivia take her last breath. She was really gone. And he could never get her back.

The funeral began. Many officers had shown up. Some who didn't even know Olivia. She was just well known and respected.

Captain Cragen was the first to speak. He was almost finished his speech before he broke down and had to stop. Alex Cabot spoke next. She cried the whole time.

Finally Brian stood up to speak.

"Detective Olivia Cassidy was more than a woman who saved lives and was dedicated to the job. Olivia was funny, and outgoing and loved doing new things. You all know Detective Cassidy. But lots of you don't know the real Olivia Cassidy. She was different than the detective. She knew how to have fun. That's what I loved about her. She was open to trying anything. Like when we were in the Bahamas a few years ago, she must have tried every sea food. She probably ate almost all the creatures in the ocean. Of course she hated all of them, but she wanted to try it. Olivia was the most amazing woman I know. I will forever love Olivia Cassidy."

Brian had more he wanted to say but he knew if he continued he would break down.

Finally the funeral was over. Olivia's squad carried her casket out of the church and lifted it into the back of the vehicle that would carry her to her burial.

Brian stood next to Cragen and Fin. They had taken Olivia's death the hardest out of everyone there. Brian was in his own world. He was not paying any attention to what anyone was saying. He didn't even know who was talking at the moment.

Brian felt Cragen's hand on his shoulder. He looked up; everyone was walking back to their vehicles.

"Let's go, Brian."

Brian shook his head. "I need to be alone for a minute."

Cragen nodded in understanding.

Brian looked down at Olivia's casket in the grave. Tears filled his eyes. He fell to his knees.

"Olivia this is so damn hard. I knew it would be hard, but this-this is painfully hard. It's been three days. Three long days and I am struggling. I promised you that I would move on. I will. But right now I just need time. It will take a while. I promise you I will move on. I miss you. I miss you so much. I wish you could be here right now. I could really use one of your hugs. I won't be able to visit you every day, but I will be here as often as I can. That I can promise you. I can't go more than three days without talking to you. I better go though, Cragen is waiting for me. I love you Liv. Rest easy."

Brian slowly stood up and looked into the ground again. That was the last glimpse he would get of Olivia's casket. He looked at her headstone. There was a space beside her name and date of birth and date of death for his. They would be together forever.

The love that Brian and Olivia had for one another was indescribable, but those who were fortunate enough to see their love knew they had witnessed something beautiful.
