Writer's Wrap is a series of short videos released on Salem official social networks accounts.
Every week, usually the day after episode airdate, Adam Simon reviews the main events of the episode, also giving some curiosities or explanations where needed. Brannon Braga and other scriptwriters are also featured, but less frequently. During the first season, Writer's Wrap were known as Inside Salem.
Since this shortcoming happened concurrently with the cancellation of the series, it's possible that it's due to social networks account management issues, although these are still updated with other content.
