While it seems Louis Litt may be gradually realizing his anger and accusations have reached a crescendo, the road to recovery and healing is rarely wrought without thorns. Viewers of the show did see Donna finally getting to Louis, but can he really forgive everyone for keeping such a huge secret from him?

In episode 13 titled "Fork In The Road", Harvey and Louis are going to travel together to see a client whom they have deep ties with. The official synopsis posted by TV Guide reveals that Harvey will use this time to his advantage and force Mike and Louis to confront their trust issues. But the most intriguing part of the episode will be a major flashback that will uncover the truth behind Louis and Harvey's rivalry. While Harvey and Louis have always had a tumultuous relationship, fans have never known the reason behind it. Viewers will be transformed to the past when Harvey and Louis were just associates pitted against each other.

Meanwhile, Mike will learn the limits of his intelligence when it comes to the law. There are also speculations that Louis will, at some point in the season, use his secret about Donna sleeping with Harvey. Why else would it be on the table? In an interview with TV Line, executive producer Aaron Korsh was questioned about whether Louis would use this secret, to which he replied, "So will it emerge again? My answer to that is yes and no. It's in the ether. It does play into things. He doesn't, at the moment, actively use it against her at this point in the last six, but it's always there. It's a piece of information that's always there for Louis." Korsh also pointed out that Louis is going through a semi-healing process and re-bonding with Harvey, Mike, Rachel, Donna and Jessica.

"Fork In The Road" airs on Wednesday, Feb. 11 at 10 p.m. on USA Network.
