When Dean scares off a big prospective client by being too dramatic, Stewart tells him maybe it’s finally time to let go of his “Grinder” persona and come down to earth. He tries to convince Dean he should go to therapy. Dean reluctantly agrees, but in typical Dean fashion, he overcorrects and begins “therapizing” the whole family, including Debbie, who is now tempted to quit her grueling job.

When Stew learns that his father is guilty, he wants to settle, but Dean tries one of his old "Grinder" tricks to solve the case. Meanwhile, Stew is concerned that he is now "infected" by "The Grinder".
