Author's Note: I apologize for taking so long to update. Hopefully, I still have my readers. Anyway, after this there will be one more part. . .I think. It's coming to an end and I promise the next chapter (and possibly the last) will be up sooner than this one was. I'll keep my word.

Part 4: Returning to Middleton

Upon arriving at Middleton, Kim thanked the man who had given her a ride and quickly ran into town. She hoped she had gotten there before Dr. Killingsworth, but she stopped abruptly when she saw an old enemy lying on the ground. She looked as if she was just about ready to pass. Her arm looked a bit swollen. Although, Kim would've loved to see Bonnie finally brought down just under different circumstances and not like this. Not by death. A pang of guilt and sorrow over took her then as she saw her classmate lying lifeless. She cautiously made her way to her as she held her breath, praying that the girl was still alive. She kneeled down and felt for a pulse and with her touch Bonnie shifted. Kim breathed a sigh of relief. The girl was still alive, but her time was running short.

Bonnie looked up at her. "Kim?" she asked.

Kim nodded. "I'm here," she said, trying to hold back her tears. "You'll be safe now. I'll get you a cure. I promise." Kim stood and was about ready to find the doctor, when a hand pulled her back.

"I was always so envious of you, Kim," came Bonnie's soft, breathy voice. Kim was astonished by this. It wasn't like Bonnie to say things like that, but she guessed that in a person's dying moments they spoke freely of their emotions, wanting nothing but peace and so there was no denying it. Bonnie was dying and she wanted peace and to achieve that peace, she'd tell Kim just how she felt.

"Don't talk like that," she said. "You'll be fine."

"I really was," Bonnie insisted. She coughed. "You seemed to have everything. Even a friend who loved you more than anything in the world. He is real, unlike my friends."

Kim appreciated her words and her kindness, but there was not enough time for this. "I have to find Dr. Killingsworth, the man who did this to you. Did you see where he ran off?"

Bonnie's breathing became labored and soon she began to wheeze. She lifted her arm and with a her limp finger she tried pointing in the direction she had last seen the man. Kim's eyes traced the path and she thanked her before she ran off in the direction of the mad scientist. She would find that man and get the cure from him is it was the last thing she did. She needed to save Ron and Bonnie too. She prayed that her family was safe at home. With every step she took, she sensed–felt–that there was danger. The more bodies she saw, the more the dread and doubt consumed her. Tears welled up in her eyes as she continued to run. She still kept her determination untouched by the consuming doubt and dread.

She saw a familiar face standing just outside her door. "You leave them alone, Killingsworth!" she shouted as the man removed his hand from the knob. He turned and with the look on his face Kim stopped. Her heart pounded in her chest. His slow, creeping, half grin held such evil mischief that she knew that her family had been injected with his poison. Her tears finally escaped her and she sobbed, placing her hands on her face as she screamed with frustration. Without much thought, she ran toward the man, wanting nothing more then to see him suffer for his actions. She would make him tell her where his antidote was.

As soon as she had come close enough, he pulled out another needle and with as much force as he could muster, brought it down toward her, but she kicked his wrist making him drop the needle. He grabbed at his wrist as he looked at her, his face twisted in pain. "Tell me where the cure is!" she shouted.

He smiled through his pain. "It's close. Very close." It was all he said.

"Where?!" she demanded as she kicked him in the face. He fell on his back, hitting his head on the door, but he was still conscious. He looked at her in a daze, but he still managed to maintain his evil grin.

"Now why would I tell you that?" he questioned playfully.

She growled before she stomped on his face. "Tell me," she said forcefully. "Or I will be forced to-"

"Kill me?" he asked, the blood from his nose dripping down the side of his face. He kept one eye closed. "Now if you kill me, Kim Possible, you'll never get your hands on that cure and another thing. . ." He paused and she waited. "You'll be just like me."

She stepped on his face again as a surge of rage consumed her entire being. "I will never become like you!" she shouted as she continued beating him. He grunted, but never once had his wicked grin faltered. She allowed all of her frustration and anger to be let lose and then at that very moment, looking at his never-faltering grin and knowing what he had done, what everyone's fate was without that antidote, she wanted to kill him. She wanted to end his life and she didn't care the cost. She'd do it, but then as quickly as the sudden thought over took her, Ron's image flooded her mind and she stopped, her foot in mid-air. She saw his body lying out there, alone and. . .waiting. . .for her to come for him. She kneeled down beside the man. "Tell me," she said as calmly as she could. Her voice was trembling from her powerful emotions. "Where is this cure?"

The man did not reply, he only grinned. But his previous wordscame back to her. It's close, he had said. Very close. She looked at the man's face. It was covered in blood. His nose was broken and his eye was swollen. She looked at his coat pocket and then back at him. She smiled. He was slightly confused. "Thank you," she said. His grin finally fell and as he opened his mouth to speak, she punched him and finally he fell unconscious. She then reached into his coat pocket and removed a small box. She opened it and a blue, vibrant liquid gleamed against the sun's setting colors. She closed it and rushed inside, but as she opened the door something grabbed her foot. She turned and Dr. Killingsworth was holding her ankle. She tried to pull away, but his strength was a surprise. He pulled her once and she fell. The small box fell from her hands and as she attempted to reach for it, a needle struck her leg. She opened her mouth, gasping. She could feel the poison seeping inside and her heart began to pound and just as the liquid entered her blood stream, it became hard to breath.

Her echoing screams could be heard a mile away, but with almost half the town laying face first on the ground and the other half hiding in their homes, there was no one to help as her screams began to die down.
