I have this headcanon that the sheriff has had scott and stiles in the interrogation room many times.
And a very vivid image of the sheriff pulling up to the station and getting out of the squad car. And by the look on his face passersby think he has some hardened criminals in the back, bank robbers, or murderers, or sociopathic dog nappers.
And he opens the door and out tumbles a seven year old stiles, arms crossed not quite right over his chest, and looking very put out and then a contrite Scott after him, staring at the ground, floppy hair covering his eyes.
And he marches them into the station and makes them sit in the drunk tank until melissa comes to collect Scott. Probably puts them in interrogation at some point, and scott nervously fiddles with the empty bag of chips from the vending machine in the hall.
And the sheriff walks in and Stiles stands up and points and shouts “YOU’LL NEVER BREAK ME!” And Scott sucking in a deep breath from his inhaler and wailing “I broke the window!” And sighing in relief.
