The next episode of Suits season 5 [episode 7] will feature some pretty intense confrontation between Harvey and Louis and doesn't look like it ends well.
Episode 7 of Suits season 5 is titled Hitting Home and will have Louis' sister, Esther, returning to the firm to "solve a problem discreetly."
In an earlier episode of Suits season 5, Louis, who did not approve of Esther getting close with Harvey, confides in him that in high school, people would befriend him [Louis] only to get close to his sister. He fears that the same thing will happen in his professional life but Harvey assures him that he has no such intentions.
The promo for episode 7 (below) shows that some tension is brewing between Louis and Esther. In the promo video, Louis is seen yelling at Esther telling her that he is not her "buffoon brother."
Towards the end of the promo, a scene between Louis and Harvey is teased. Louis reminds Harvey of a promise he made. Harvey warns him to watch his words. Louis tells him that he is a "lying, cheating..." and before Louis can complete his sentence, Harvey appears to raise his hand to slap him and the video ends. (via Yibada)
The official synopsis for episode 7 reads: "At Jessica's behest, Mike teams up with Jack Soloff to co-counsel a case, and despite their history the two come to a surprising understanding.
Meanwhile, Esther Litt returns to P.S.L. to solve a problem discreetly, but Louis rarely handles anything quietly – especially when it comes to family. And Donna and Harvey try to get their friendship back to normal, but Harvey has a hard time stomaching Donna's 'friendly advice.'"
Suits season 5 episode 7 Hitting Home airs on Wednesday (5 August 2015) on the USA Network.
