"Suits" has reached the end of the road for this season and is already gearing up for season 5. But before season 4 ends, Harvey Specter and the gang are in for one very challenging episode. Not to mention, fans are going to be treated with extra minutes in the finale episode, too. 

Recently, "Suits" creator Aaron Korsh answered questions over at Twitter and confirmed that the finale episode will feature extended minutes. Further, when Korsh was asked if Donna and Harve are going to end in good terms, he said "Yes." 

The preview for the finale episode shows Donna confronting Harvey about his "I love you" and she looks very confused. There is also a scene where Louis is telling Donna how lucky Harvey is to have her. Will Donna be caught in a love triangle? 

Season 4 episode 16 is titled "Not Just A Pretty Face" and the official synopsis goes: 

"When SEC investigator Sean Cahill fails to link his corrupt boss Eric Woodall and corporate raider Charles Forstman, Harvey must revisit his own uncomfortable past in order to find a way to put them away for good. Mike and Rachel confront the fact that, while Rachel is Harvey's associate, Mike is his guy. And Donna helps Louis with an unexpected crisis." 

Based on the synopsis, Cahill makes a guest appearance but he's alone. Harvey's brother Marcus Specter  appears in the episode, too. He is played by actor Billy Miller and his character is the complete opposite of Harvey. What brings him to town? 

There's also that question if Harvey will even agree to help Cahill bring down Woodall. Fans know how much Harvey hates Woodall, but will this be enough for him to work with Cahill? 

Meanwhile, "Suits" is set to start filming for season 5 this spring, reports CarterMatt. It will most likely return in summer, which is the usual premiere date for the show. 

The finale episode for "Suits" season 4 will air at 9 p.m.on Wednesday, March 4, on the USA Network.
