Plot summary
As the trial continues, Harvey calls Mike in as a witness, Faye insists that Harvey take the stand against Samantha the next day in order to win their case. Harvey then discloses to Mike the deal he made with Faye in order for her to leave the firm, and admits that he never stopped trusting Mike; who then suggests one last con together to stop Faye. Mike then offers Samantha another witness to testify against Faye: Katrina, who initially refuses because she is unhappy about the way Harvey treated her, but after Alex talks to her, she tells Faye that she will claim that Faye asked her to spy on Samantha and tamper the evidence. Furious, Faye orders Harvey to make sure Katrina is taken off the witness list, though he counters back and insists that Faye put their agreement in writing.
When Faye arrives to sign the agreement the next morning, Samantha and Mike yell at Harvey for tampering with their witness and a brief fight erupts. When Faye intervenes, Gretchen, whom Louis came to the previous day, swaps out the documents at the last second, revealing that the "fight" between Harvey, Mike, and Samantha was a distraction, and resulting in Faye unknowingly signing a document admitting to witness tampering, essentially ousting her from the firm at the group's urging. She still refuses to back down until Harvey privately persuades her to leave, telling Faye he will give her what she wants (himself) but not the way she wants it. After Harvey tells the group that Faye is packing to leave, Louis rehires Samantha at the firm.
The next day, Louis and Sheila get married with Stan officiating their ceremony, only to have Sheila go into labor, causing them to go to the hospital. On the spur of the moment, Harvey proposes to Donna and they marry on the spot. After Sheila gives birth to a daughter, Harvey and Donna reveal to Louis that they are resigning from the firm and moving to Seattle to work with Mike. Though this is what Harvey told Faye, he admits that while he likes working in the grey, he wants to do it for the good guys.
Katrina is promoted to named partner, making the final name of the firm Litt Wheeler Williams Bennett. Before leaving for Seattle, Harvey is visited by Mike; who "interviews" him for his new job, in the exact same fashion as the very first episode, only this time, the roles are reversed. After the goodbyes, Harvey takes one final look around his office before leaving to begin the next stage of his life in Seattle.
