Scott gets a midnight call; something's wrong with Stiles and Derek - something that leaves the two comatose and in a nightmare of a different kind. A little banshee power tossed with some supernatural sickness, topped with a generous serving of TW bromance. Spiced with: Sterek if you squint, brother!Scott, hurt!Stiles, caring!Darek, anchor!Lydia, advisor!Deaton. (I'm so lame...)
