Robin Hood, Peter Pan and More Returning for 'Once Upon a Time' Series Finale

In season 7, Once Upon a Time has moved far away from the series' origins and original characters. However, that group is far from forgotten. A huge cast of returning characters and actors have already been announced for the show's upcoming series finale. While some notable characters are still missing (or just unconfirmed), the end of Once Upon a Time looks it will honor the whole series, not just the new season.
