Following his breakup with Tara, Louis starts terrorizing the associates. His behavior raises red flags with Rachel, Donna, and Gretchen. Donna has figured out that what she wants is a seat at the table as a senior partner. She uses the situation with Louis to prove to Harvey that she deserves it after all these years of being a key person in running the firm without getting credit. Harvey agrees to name her senior partner, but has to tiptoe around telling Louis. As Rachel convinces Louis that he needs closure with Tara, he allows Rachel, now a lawyer in her own right, to step up and take over the associates from him. Meanwhile, Mike and Harvey team up again to prove to one of Jessica's clients that the firm can handle his case now that Jessica is gone. Harvey has a hard time filling Jessica's shoes and pursues a romantic relationship with his former therapist, Dr. Paula Agard. Mike gives the legal clinic half a million dollars, but his returning to PSL doesn't sit well with his former colleagues, especially Oliver.
