A/N: This chapter is short just to warn you.

Kate stood there in bewilderment, staring at the person who murdered Casey. It was Brooke Thompson… That girl Sam cheated on Casey with, but what did she have against Casey?

Brooke stood in front of Kate pointing a gun to her. "Why couldn't you just mind your own business, you clone freak?"

"Why, Brooke," Kate said hesitantly.

Suddenly Derek and Sam came bursting through the door, they both saw Brooke holding a gun and came to a rapid stop. They also saw Emily's lifeless body on the ground.

"Emily," Sam whispered sadly.

Derek said nothing, but expressed much sorrow.

"Ah, here we are… All together, isn't that sweet?" Brooke said pointing the gun at all three of them. "Now that you all are here, I think it's time you know the truth about Casey McDonald." Brooke began. "I used to go to her private school before she moved here. She was such a beautiful person, straight 'A' student, star talent, class president. I tried to talk to her, but she wouldn't give me the time of day!"

"Brooke… did you love her?" Kate asked.

"Yes, I did… I changed schools for her and then I find out she's dating this prick," She pointed the gun toward Sam and he flinched. "So I seduced him, recorded Sam and I having sex and showed it to the whole school. I wanted her to feel the pain I felt when I found out she had sex with Sam."

Kate looked at Brooke severely. "You monster…"

Brooke pointed back to Kate. "No, she was! I followed her up here one day and admitted my feelings for her, but she said she loved you," She pointed the gun at Derek. "I tried telling her that I was meant for her, not you, Derek Venturi. She insisted that you loved her back. I tried to kiss her to prove to her that we were meant to be, but she resisted me so I figured if I can't have her no one will."

"So you pushed her off…" Kate finished for her.

Brooke pointed back at her and said sarcastically, "Aren't you a smart little cookie." She pointed back at Derek, "It was you! You were never good enough for Casey! You are a womanizer!"

"No one has to die tonight, Brooke," Derek stated.

"Oh, but you really do…"

Kate saw that Brooke was going to pull the trigger and quickly dove in front of Derek right as she pulled it. Kate fell to the ground in pain and Derek lunged at Brooke knocking the gun from her hands. It fell to the wet ground and Sam went to pick it up, but Brooke tripped him and went after the gun herself. Derek grabbed her foot and pulled her towards him, "I never hit girls, but in your case I'll make an exception." He then punched her hard enough to knock her out. He let her lay there unconscious as Sam retrieved the gun, then they both turned to Kate, who was wounded laying there on the cold wet ground.

Derek held her in his arms and said to Sam, "Go call an ambulance, hurry!"

Sam nodded and ran off to do the deed.

"Why'd you go and do that for, Kate?" Derek asked.

"I couldn't let the main character of the show die," She mused; suddenly a sharp pain was felt in her stomach. She knew she didn't have much time left, she knew her fate and accepted it. At this time the weather had calmed down and Kate could see the tears in Derek's eyes clearly. "Hey, none of that now, be happy. We found Casey's murderer."

He nodded. "I know, but…"

Kate knew what he was going to say. "I'm going to miss you too, Der." She could feel her body failing, she could feel her heart pounding in her chest, beating it's last. "I… love you."

He smiled vaguely and nodded. "I love you too."

"I will never forget you." she breathed.

He brushed her pale cheek with his hand and replied, "And I will never forget you, Katelyn Thomas."

There was a slight grin on her face as she inhaled… then exhaled… one… last… time… Her body just lay there inert in his arms as he wept silently burying his face in her neck.

She was gone… Katelyn Thomas had finally gone home…
