I originally had this idea in my head to do an homage to Stand By Me, in the beginning. Kids go out and search for a body in the woods, and it’s not quite what they expect. That’s how it started.
What if the Doctors have been grooming him since he was little?
What if his reaction (or lack thereof) to his sister’s death was a test of the procedure they’ve been using to suppress Theo’s more inconvenient emotions? (Didn’t Theo’s sister die when he was like 10?)
What if Theo passed the test, so the Doctors whisked him away from Beacon Hills to continue his preparation?
What if he wasn’t the only one they’d been grooming?
What if Claudia had been onto something when she said she was afraid of how Stiles looked at her (when he was 10)?
What if Stiles just got lucky and the procedure didn’t last?
