Sterek AU: Derek is going back to Beacon Hills for the first time since the fire when his truck breaks down. He’s miles from anywhere so he calls the only person he still knows in Beacon Hills, a sheriff who gave him his number after the fire and told him to call if he ever needed anything. Miraculously the Sheriff still has the same number and he promises to send the cavalry. When the cavalry arrives however, it looks suspiciously like two teenage boys, one of whom seems to have developed a crush on Derek. Perfect.
