Sequel to Bringer of Terror. When Blair Sandburg calls in the Winchesters for help with a weird case, Dean and a recently re-souled Sam see this as the perfect chance to get back in the saddle. But it might turn out that at least one of them could be a target for this new evil. Set three years post-series for Sentinel and post 6x12 for Supernatural. Case fic.
Case fic. A possible hunt sends Sam and Dean to Cascade Washington where they run into an unusual investigative team looking into the same case. (set Season 1 for Supernatural, Season 2 for The Sentinel)
Dean didn't become a Sentinel until after he gets back from hell, and panicked from all the sensory overload and thought he was going crazy from his trip to hell. But Sam has read Everything Ever and suspects what's going on, needs to confirm it and so he kidnapped the world's expert in Sentinels. Jim is not amused.
An unexpected meeting Ellison and Sandburg would never forget again.
