Foresight

Chapter 78: 5-11

"We should stop them before they kill the boy" Claudia said after watching the two boys beat the crap out of Theo. "Not yet" Peter said in glee, finally out of the hate sight of everyone in the room. "I think not" Scott sighed and pulled the two off the chimera. Liam huffed and stopped but Stiles kept on kicking. "This is for my friend, my father, my car and finally Lydia" he growled and kept kicking him.

After finally calming down, everyone returned to their seats. "I wonder where Sky was this time" Laura said to Derek who shrugged. A piece of paper flashed in front of her and she picked it up. "I was in the bathroom" she red and deadpanned. She through the paper behind her and somehow hit a groaning Theo on the face and resumed watching.

At some future point in time, Lydia Martin has a vision of standing in a fast-moving water. Dr. Valack is guiding her through the vision and asking her to describe what she sees. It's night and she can see the bridge where we last saw a young Theo watching his sister Tara Raeken die. Valack urges Lydia to give him more and more details because he says he needs to know why Theo let his sister die. Theo's sister rises from the water. She has a large gaping hole in her chest through which we can see her ribs.

"I don't think hypothermia can do that" Mason pointed out. "I think Theo could" Stiles mumbled in disgust.

Her heart is gone. Once Lydia, with a fresh trepanation hole in her head, relates this news to Valack, the doctor speculates that Theo wanted her heart for a transplant to make himself a biological chimera. He says leaving his sister to die in the cold water in hypothermic conditions would keep the organ viable.

"I was right" Stiles said not at all happy. Against his side was Lydia Martin, who had seen the hole in her skull. She was shaking at the thought of the pain that would cause her. The only comfort she could feel from all this was that this wouldn't happen a second time since they knew what was going to happen. And the arm around her that held her gently yet firmly, like an anchor to reality.

The Dread Doctors are shown with the heart and a young Theo prepared for surgery. Valack doesn't understand why the DD wanted Theo, "A ten-year-old willing to kill his own sister." A groggy Lydia asks Valack why he cares. He explains that Theo was the first step in the right direction for the Dread Doctors. He explains they are para-scientists who have prolonged their lives and twisted the laws of nature in an effort to create the "perfect killer." He says they've now reached that goal but Lydia says Theo doesn't know who their last chimera actually is. Valack says that doesn't matter because there is a reason they chose Theo, a reason he failed and a reason they changed their methods and finally succeeded. Valack says it all starts with Theo.

"And hopefully it would end with him" Scott thought. He did not wish to kill the boy but if he became a threat to his friends as shown in the memories, he would have no choice but to do it, even if it meant he would never be an Alpha.

Still in the future, Tracy disables an Eichen House guard with Kanima venom. Josh disarms one of the guards by grabbing his taser and absorbing the electricity from it. Corey becomes visible from where he had been camouflaged against the lobby wall.
