"Suits" season 4 spoilers reveal that Louis Litt finally got his wish to become partner but what would it mean for Mike Ross whom he promised to destroy? Meanwhile, Louis will be joining forces with Hardman for a yet mysterious case.

According to Cartermatt's season 4 spoilers for "Suits:"

"Louis Litt has been made partner. Now, the characters are working under Pearson Specter Litt, and Mike Ross is basically at the mercy of a pretty intense, sometimes crazy man who holds moral authority first and foremost ... even if he does not always choose to follow it himself," it said.

Fans should remember that Louis found out about Mike Ross' secret that he doesn't have a law degree. Not only that, Jessica Pearson and Harvey Specter also helped covered that fact. In the mid-season finale back in August, Louis Litt used what he found out to threaten Jessica to put his name on the wall as partner.

Rick Hoffman previously told Buddy TV:

"I think what brilliant cliffhanger that the writers leave you with is Louis up until that point has done everything with his T's crossed and his I's dotted," he said. "And now that he sees that has completely gotten him nowhere and is now gone through this threshold where he can't turn back. Once again, I'll say the possibilities of his moral fiber and core, how broken it is, that can change anything here on in. I wish the people at Pearson Specter good luck dealing with this guy."

Meanwhile, creator Aaron Korsh tweeted on December 8: "Will Louis be joining forces with Hardman again even tho Hardman only used him the last time? He will but not how you think.."

He also said in the Twitter Q&A that the remaining six episodes of the series will be a departure for what fans have been used to for so long. The showrunner said that some of the cases will last "more than one episode."

Watch out for "Suits" season 4 spoilers which will be published here as they come along ahead of the return date on January 28.
