This is the third story in my crossover series. You do need to read Robin's Sister to understand this, but you don't need to read my other two crossovers. This isn't really set at a specific time during the series. Thanks for reading!

After a Mysterious Guest in Beacon Hills Derek comes home Beaten and Bloody. Trouble Starts at School when two new Arrivals come. Then...Everything goes Crazy!
