After more than a month hiatus, Grimm returns with an all new episode “Eve of Destruction.” Originally titled “The Return,” and also set to air last week on January 22, Grimm writers and producers seem to have taken their time with the reintroduction of Bitsie Tulloch back into the series. I never believed Juliette (Tulloch) had died but what transpired in “Wesen Nacht,” coupled with her surprise “Eve of Destruction,” sets the stage for an all too intriguing episode.
