Last episode with 'Rob Morrow' (Joel Fleischman) in the opening credits and his final appearance on the show.
This marks the final appearances for two recurring characters: Adam, played by Adam Arkin and Bernard Stevens, played by Richard Cummings Jr. Incidentally, both their characters were introduced in season 1's "Aurora Borealis: A Fairy Tale For Big People". The two men didn't share any scenes in either episode.
