Since "Suits" came back for its midseason premiere, the episodes have dealt with Louis Litt's rage and anger toward his colleagues. In last week's episode, Louis has finally forgiven Mike Ross and it looks like the show can now move on from the emotional storyline. It has been a while and fans are gearing up to see some new cases. 

This week, it looks like fans are going to get their wish. With personal issues out of the way, the team is ready to take on real-deal cases and, of course, win in whatever way possible. In the upcoming episode, the focus is on Mike as he takes a case that hits close to home. 

In episode 14 titled "Derailed," the official synopsis is:

"When Mike takes a humanitarian case with the potential to jeopardize firm business, Harvey must decide how much to rein in his associate. Meanwhile, Jessica wrestles with the distance she's been forced to put between herself and Jeff Malone. And Louis fights to get the respect a name partner deserves." 

As for Harvey, CarterMatt says that he will have to decide whether he'll take the Daniel Hardman route when dealing with associates. And then there's the repercussion of Jessica's lie to Jeff — is it finally taking a toll on their relationship? 

Meanwhile, the promo for the episode shows a much more interesting side of the episode. It looks like Donna will be in big trouble. "The truth won't set her free," the primary text in the promo reads. 

In the beginning of the promo, Harvey says, "You did something sketchy."

Then it cuts a shot to Mike saying, "If Harvey figures out what is going on, he's gonna pull the plug."

And then there are several shots of Donna going into the file cabinets and then looking very worried. What could be the cause of her worry?
