Later, Mike is seen saying, "things can change in a blink of an eye." Donna and Rachel look anxious and worried. Harvey wants to know from Mike what he did. The synopsis of the episode hints that someone is trying to "poach" the clients of Pearson & Harvey.
Episode 10 of the current season is expected to feature a couple of recurring characters. When asked if the mid-season finale will have any familiar faces, Aaron Korsh, creator of "Suits," said on Twitter: "We will. In fact, more than one recurring character will show up..."
The previous episode of "Suits" Season 4 saw Harvey and company finding out that Woodall is in bed with Forstman. It is Louis' tip-off and suggestion that helped Harvey and Mike nail Woodall. They also used that as leverage to stop Cahill and the SEC from coming after them and the firm. Jessica had made up her mind to fire Louis because of his past and this season's follies. Harvey was unable to change her mind. Louis resigned and left before Harvey and Donna could meet him and say their goodbyes. He asked them to take care of his home [the firm].
The synopsis of the episode suggests that outside the firm, Louis will find it difficult to fix his personal and professional issues.
Meanwhile, there is a possibility that Logan will feature in episode 10. When asked if Logan, the man who caused the two episode rift between Rachel and Mike, is officially gone forever, Korsh said on Twitter: "It's #Suits, no one is officially gone forever..."
Below is the official synopsis of "Suits" Season 4 episode 10:
"Harvey and Jessica take measures to protect the firm from an outsider trying to poach their clients, and Louis struggles to get his personal and professional affairs in order."
The remaining six episodes of "Suits" Season 4 are expected to air either in winter or spring. USA Network has renewed the show for Season 5.
