On instagram, I had the idea of a crossover. This story will be short (slightly over 10 parts) . . Sam and Dean are investigating the not-so-recent killings of people and animals in Beacon Hills, while staying at their cousin's house there. Stiles' cousins come round to stay for a while, saying they are here to research in Beacon Hills and wanted to stop by for a visit to their half- uncle and cousin. This means that Stiles has to hide the reality of his friends and boyfriend to them and it's proven quite difficult.
