'Suits' season 4 spoilers: Harvey's father guest stars, show creator talks about remaining episodes and finale

Facebook/ Suits

Every "Suits" fan went from loving Louis Litt at the start of season 4 to hating him when the mid-season premiere went on air. He had a huge card in his hand and he used it to get what he wanted. But since he set his eyes on the goal too much, he was blindsided at the end. Episode 11 ended with another win for Jessica, Harvey and Mike's side ... at least for now. 

Episode 12 is titled "Respect" and, according to the official synopsis, Professor Gerard (Harvey's father) will make his way into the episode:

"Harvard ethics professor Henry Gerard seeks Harvey's help with a case that requires a lack of ethics to win. Mike, meanwhile, does his best to not be spotted by the professor, whose class he never took; and Louis tries to wine and dine a socialite CEO." 

The show's creator and executive producer Aaron Korsh explained to TV Guide that this episode will feature the aftermath of what Jessica did to Louis and her lie to Jeff Malone. However, Carter Matt obtained a snapshot of Harvey and Donna together and they look very serious. Did Donna's confession to Louis have something to do with it? There's always that risk of Louis using the truth against Donna and Harvey, but this time, Korsh assured fans that this admission will deepen the bond between Louis and Donna. 

For episode 13, "Fork in the Road," the synopsis goes: 

"Harvey and Louis travel to see a client to whom they have deep ties; and Harvey takes advantage of the time to force Louis and Mike to confront their trust issues. In other events, in a flashback, the root of Harvey and Louis's competitive relationship is explained; and Mike learns the limits of his intelligence when it comes to the law." 

Could Mike and Louis really wipe the slate clean? Or will Louis continue his onslaught of retaliation to everyone who betrayed him? Korsh explained that "forgiveness is a process." 

He also shared, "Louis is probably still grieving over hurts from 10 years ago. Episodes 12 and 13 continue his process of acceptance or coming to terms with the situation. It's not finished yet, but there's more to come." 

As for the impending season 4 finale, Korsh explained that the first half will show the "emotional fallout" after Louis discovered the truth. But by episode 14, where Professor Gerard comes back, the show will move on and handle a serious case. 

In addition, the season finale will feature Cahill and Forstman, perhaps working together to bring down Harvey? Korsh admitted that the finale will be a flashback episode, showing how things got eery between Forstman and Harvey. And of course, just like any season finale, there will be a twist. But this time around, there will be "a twist or two" said Korsh. 

"Suits" season 4 episode 12 airs Feb. 4 on The USA Network.
