Another Apocalypse

A strange case leads the Winchesters to New England. To save the world they have to join forces with astrophysicist Jacob Glaser (as portrayed by Misha Collins in S.A.). While investigating, both Sam and Dean tie unique bonds with the stranger - will it bring them closer or tear them apart? / Can be read as a simple SPN AU. Destiel-ish, no Cas though. THE apocalypse didn't happen.
