AU: After Stiles accidentally kills Donovan, he calls the police in guilt. Only heavy breathing can be heard from the end of his line as the call cuts. Lydia can sense that there’s something wrong. She calls Stiles to see if he’s okay, but he doesn’t answer. She drives to the school and gets confused to why Stiles’ jeep is broken down and abandoned. She heads towards the school library, where she finds Donovan stabbed with a metal beam. Stiles runs back into the library after seeing Lydia’s car in the parking lot. He walks in to find her absolutely shocked, but she can tell the way it happened was an accident. Stiles stands in place completely frozen, staring at the dead body ahead of them. Lydia keeps telling Stiles it was self defence, it was an accident and that they need to flee the school right now. They run through the hallway holding hands and make it outside. Stiles is still shaken up about the event, he wants to cry and fall to the ground. Lydia could see the guilt and fear in his eyes and all she could think of doing was to give him a hug, to let him know he’s not alone. But shortly after, they hear police sirens in the background and they sprint to the jeep. The police car pulls into the school parking lot and that’s when Stiles turns the head lights off and backs away into a corner. With his bloody hands on the steering wheel he’s trying to slow his breathing but he can’t. Lydia’s feeling so scared for him, she reaches over to hold his hand. When the police leave with no body, Stiles turns his radio on and they both hear that no body was found. They go back into the school and find out that someone took the body. They drive back to Stiles’ house where Lydia gives him a little pep talk. He still believes he murdered Donovan, and begins to break down while writing on his mystery board. Lydia stands beside him to see what he wrote, she doesn’t know what to say at that very moment. It wasn’t his fault but he doesn’t understand that. She gives him another hug. PART 1
