Apple TV+ series co-creator Bill Lawrence has revealed that Season 4 of Shrinking will feature "a new story with the same cast" for the final episode of the show. The announcement comes ahead of the Season 3 finale on Wednesday, which debuts on the streaming platform. Lawrence clarified that the show's current storyline is a three-season story on grief-forgiveness, and he wanted to stay true to the original pitch. The current cast includes Jason Segel as therapist Jimmy Laird, who struggles to reconcile his relationship with his daughter Alice while dealing with the death of his wife.
