This is just a short fanfic that I thought of at three in the morning. I wrote it on my notepad app on my phone, so here goes.

Reid's tears cascaded down his pale bruised face. He pulled at his restraints as the cloaked man stood over him. He felt the trickle of blood come down his wrist

from where he had rubbed it raw. His breath hitched as he saw the glint of the copper stained knife. His eyes dilated as the man brushed it against his

exposed shoulder. The man placed more pressure onto the knife, and dragged it across the pale skin. Reid moaned in pain, feeling the warm viscose liquid as it

dripped onto the cement floor.

"Please, sto…" His pleading was stopped short as the knife plunged into his shoulder, and trailed down into his chest. A loud popping noise echoed through the

empty cellar, and was followed by an anguished cry. The knife was twisted, and a gurgled scream freed itself from his bloodied throat. The crimson life source

flowed freely from the jagged hole. Reid could feel as his right lung began to fill with an alien substance. His body was racked with pained coughs as his lungs

tried to rid themselves of the invader. Bright red drops appeared on his chapped lips, and revealed the damage done. His mind began to fog over, and his

extremities became numb. He could distinctly feel the stinging of the knife entering and leaving his body continuously. Black dots began to dance across his

vision, bringing a smile to his lips. For some reason, the small imaginary brought him joy in the dreary situation. His mind cleared momentarily, and he realized

that they were going to be too late. This unsub only held his victims for a short period of time, three days maximum, and those three days had come and gone.

The luminous moment left, and Reid returned to perceiving the world through a thick film. A sudden pain in his chest caused him to cry out once more before he

fell silent, his head lolled to his right. His eyelids began to flutter as his mind started to shut down. He could barely feel the blood as it climbed his throat and

leaked through his chapped lips. Reid knew that there was no cheating death, and from recollecting his previous encounters, he had already deceived death on

multiple occasions. Reid let his eyelids slip close, and his body sag. He welcomed the darkness like an old friend as it caressed him in its grip. His breathing

slowed significantly, and then stopped altogether. His heart gave a few last beats before stopping eternally. Seconds passed, and Dr. Spencer Reid was no

more.

Ok, so I don't know if I should continue, its up to you guys if you want to see reactions, and what basically comes next. Love you all!
