Shonda Rhimes confirmed that the Kate Walsh-led Private Practice and firefighter-centric Station 19 (both available to stream with a Hulu subscription) weren’t the only shows she’s thought of over the years to continue certain characters’ stories outside the hospital. When asked about what other series she’d conjured up, Rhimes told EW:

Grey's Anatomy, now the longest running primetime medical drama in American television history, was well into its seventh season — and therefore had nearly 150 episodes under its belt — when it decided to do a musical episode.

Before decamping to Netflix, Shonda Rhimes considered creating a spinoff for ABC hit "Scandal" focusing on Eli Pope (Joe Morton) and additional spinoffs for "Grey's Anatomy," including one that would have revolved around Derek Shepherd's (Patrick Dempsey) four sisters.
