Buffy spun around and saw Angelus holding a knife. She was really scared but had to hide it from Angel. He was really good at using it against her.
"Angelus." Buffy said "Long time no see."
"Always a pleasure to kill you, lover."
"So, the Slut-O-Rama gave you a happy ?"
"You mean Faith ? Yeah, she did. What's up with you Slayers and necro-boinking ?"
"None of your buisness. Now let's fight."
Buffy started with throwing her foot in Angel's stomach. He couldn't be bothered to fight back so he just stabbed her in the ribs. Buffy tried to fight back for a little while but it was useless.
Spike expected Angelus to be in tonight, so he went out earlier than usual. He was close to the graveyard when he saw Buffy and Angelus fighting. He started to walk towards them, just in case Buffy needed some help. That's when he saw it, that's when he saw the knife. It was already covered with blood, he could smell it. Warm blood, Buffy's blood. Then Buffy fell down. She couldn't fight anymore. When Angelus saw the anger in Spike's eyes, he couldn't do anything but run away from the scene. Spike ran like he had never ran before and was by Buffy's side in no time.

"Buffy. Buffy ?" Spike called, "Are you allright ? Buffy, please, answer me."
Buffy looked at him with tears in her eyes. She was going to die tonight, and she knew it. She could feel the life being sucked out of her.
"Spike... I'm hurt. I'm really hurt."
"I know, I know. But you're gonna be just fine. I'll... You'll be just fine."
"No I won't, and you know it. But it's okay, I was prepared for it. And you're with me, which means a lot to me. And..."
"No. No ! You are not going to die. I'll get you to a hospital. Buffy..."
"Spike, it's too late."
Spike was starting to cry as he realized the one and only woman he loved was being taken away from him.
"Buffy, you can't leave me, I can't do this without you. I can go on with... I love you. I love you, Buffy. I've never loved anyone before as I love you. You're everything to me. Everything."
"Spike, my God. Could your timing suck even more ? I love you too. I've loved you for so long. I... Hold me, Spike."
"Of course, luv. I'm so sorry. I am so very sorry. Sorry that I didn't tell you I loved you sooner. Sorry I didn't watch out for you as I was supposed to. Sorry... I can't do this, Buffy."
"Sure you can. You'll get through this, Spike. And you'll get on with your life. And you can watch out for the new Slayer. You can train her, and help her and..."
"No, I don't want to. I wanna stay with you. Forever. I can make you a vampire right here, right now. That way, you and I can be together."
"No, Spike. I can't, and I know that you don't wanna do this. Spike, I love you."
"I love you too, Buffy. That's why I can't do this."
"I just want to know that you'll be okay."
"I won't, Buffy. I won't be okay ! Not without you !"
"Spike, please, tell me you'll be okay."
"I can't, Buffy. I... I just love you so much. I can't stand watching you die without doing anything. If you die, so will I."
"No you won't and you'll... Spike, I'm cold."
"Here, luv. Take my jacket."
"Tell Giles to... tell my Mom and friends and... make sure that Faith gets what she deserves. Now please just hold me."
Spike hold Buffy so tight, she could barely breathe. They were both in tears, realizing that the moment they found out they were in love, they were torn apart. Then, after holding her for a while, Spike understood that Buffy was dead.
"Buffy... Buffy ? No... No !"
For a moment, he just layed beside her, crying. Then, he got up and started looking for Angelus. The bastard had to die for what he did to Buffy. Spike looked for him the whole night. He finally found him on the other side of the town, hiding. Spike just walked right into the bar Angelus was hiding in. He grabbed him by the jacket and litterally dragged him out.

"Spike !" Angelus yelled when Spike finally let go of him, "What the Hell do you think you're doing ?!"
"She's dead, you fucking bastard ! You killed her !"
"What ? You mean the Slayer ? Yeah, I killed her. What ? You wanted to do it yourself ?"
"You are gonna die for what you did, you asshole. And it's gonna be slow and painful."
"What are you talking about ?"
"I loved her, you fucking ..."
"Hey ! Watch your language !"
"I say whatever the bloody Hell I wanna say, and I wanna say that you're a fucking bastard. Why did you kill her ?"
"You know why. She is, or should I say was, the Slayer."
"I loved her ! And she loved me !"
"Loved her ? Whoa ! Did you hit your head or is it Drusilla's influence ?"

Spike took out some holy water he had found in Buffy's bag and threw it at Angelus. Angelus, who was taken back by the burn, was now down to the ground. Spike took out his stake and stabbed him in the leg at first. Then his stabbed his way up to the heart. But he didn't dust Angelus, he broke his knees and left him there in the alley. Then he made sure that Faith would die, by sending some vampire to the motel where she was staying. After that, Spike walked back to where he left Buffy, to die by her side. He sat down next to her, holding her in his arms.

"I love you, Buffy. You are everything to me. That's why I can't go on without you. I know that you didn't want me to do this, but it's only solution for me. You and I are gonna watch our first and last sunrise."
Spike held Buffy in his arms 'till sunrise. He wanted Buffy to be the last thing he saw before he died. Again.
