Criminal Minds Series Rewrite: Season Four

... And Back: Final Part

Derek and Emily are working with the Bloodhounds and walking around the property trying to find Kelly and Lucas. It's weird to think you've been with the team for over four years, working nonstop, and these two brothers were out here killing eighty-nine people without you even knowing.

Well, you know now and it's going to stop. However, no matter what you do, how hard you work, or how good at your job you are, there will always be someone out there hurting people for fun. Your job is never going to end.

Some of the Bloodhounds found scent markings on some trees but lost them when they reach a small stream of water that runs in the back of the property. If the dogs lose the scent for good, it's going to be like searching for a needle in a stack of needles.

Meanwhile, Penelope is working hard inside the house trying to figure out what's really going on here. No one kills eighty-nine people and counting without some kind of reason. It doesn't take long to figure out what Mason is researching, and it's actually shocking considering what's going on here.

Mason has been looking for a cure for his paralyzed body. He needs stem cells from people in order to cure himself, but they've all been unsuccessful experiments. Mason deems it right because the people Lucas took were transients, prostitutes, and drug users. He wanted to give their lives purpose by being part of a revolutionary cure.

He claims it's science.

Lucas has drawn what their lives have been like for the past eight years. He's the reason why Mason is how he is. Lucas accidentally pushed Mason down something that paralyzed him, so Mason blames and faults him for something that was an accident, so he has his chunky younger brother kill to help cure something that was Lucas' fault.

You and Spencer leave the barn to tell the others what you've found.

"They were doing experiments for spinal regeneration. He was trying to fix himself," Rossi says.

"How?"

"Stem cell research."

"Wait, this equipment is far too unsophisticated. There's no way it would have ever worked," Spencer says.

"You were a prosecutor, Hotch. Could you convict this guy? A quadriplegic who clearly never touched any of the victims?" you ask.

"I don't know. We need to concentrate on Kelly. We can't worry about the other stuff right now."

"Son of a bitch. He might get away with this. Come on, Rossi. Let's talk to Mason again." You look to the right and see Will leaning against the pig pen just listening in. You hope he doesn't do anything stupid. You and Rossi walk back inside the house and over to Mason who has a slight smirk on his face. "Tell me about how you got hurt."

"Does it matter?"

"Humor me."

"My brother pushed me out of the loft. I wanted to sell the farm. I had just finished medical school. It would have given me a nice down payment on a practice in the city, but the farm was all he knew. He doesn't handle anger very well."

"Is that why you hate him?"

"Hate him? He's done nothing but take care of me every day since then."

"You said not to even try talking to him if we find him. That sounds like you want us to kill him, right Rossi?"

"Sounds right to me."

"That's not hate. That's a favor. My brother couldn't survive without me."

You and Rossi leave the room to join Penelope in the next.

"Did you find anything else?" you ask.

"Nothing that'll help find his brother. There's a cell phone he calls dozens of times a day, but that appears to be off. I tried to activate the GPS locator on it, but I think it's an old phone so that's not gonna work either."
