Accidental Downer Ending: Season 2 ends in a cliffhanger, with Ethan, Benny, Sarah, and Jesse seemingly getting caught in an explosion that took out the season's Big Bad. With the show's cancellation after Season 2, it's unlikely that there will ever be an official resolution to this series.
Word of God: Mike Kiss (a writer) agrees with Vanessa Morgan (plays Sarah) that Ethan and Sarah have progressed to more than friends by the end of Season 2.
