'Suits' season 6 news, spoilers: Upcoming episodes will reveal more about Frank; Mike will find an ally in jail

The long-awaited "Suits" season 6 premiere left viewers with lots of unanswered questions.

At the end of the previous season, Mike (Patrick J. Adams) took a two-year deal for fraud so that Harvey (Gabriel Macht) and Jessica (Gina Torres) wouldn't have to go to prison.

In the season opener, which picked up right where the season 5 finale left off, Mike spent his first night behind bars and met Frank (Paul Schulze), who wants to use the former faux lawyer to get revenge on Harvey.

Meanwhile, Harvey, Jessica, and Louis (Rick Hoffman) scrambled to save Pearson Specter Litt and found themselves being sued for millions of dollars.

So who is Frank and how big of a threat will he be to Mike? Will Harvey, Gina, and Louis be able to successfully defend themselves against the lawsuit filed against them?

Speaking with Entertainment Weekly, "Suits" season 6 showrunner Aaron Korsh dished on what the following episodes will reveal about Frank and how Mike will defend himself from the new threat.

"Obviously, the guy is intelligent, devious, cunning, able to act very sincere when he's not being sincere," Korsh said. He also teased that fans will "find out more about what his crime was and what he's capable of as the season progresses."

According to the "Suits" boss, viewers will find that the character is capable of "physical and mental intimidation and harassment," which Mike will have to deal with.

In an interview with TVLine, Korsh said that while prison will pose many dangers, Mike will also find a helping hand.

"Yes, Mike will find an ally," he said. "He's resourceful, he's intelligent, and he's not without his own attributes to aid in surviving here, and he's got some friends on the outside. The season is somewhat about Mike navigating his way in there while he's got someone that's out to get him."

"Suits" season 6 airs Wednesdays at 9 p.m. ET on USA.
