Suits season 4 finale airs this Wednesday SUITSonUSA/facebook

The final episode of Suits season 4 airs tonight (4 March, 2015) and fans are eagerly waiting to see how the finale of this rather intense season unfolds.

What's in store for Harvey and Donna?

In the preview video (below), Donna is seen telling Harvey that he ran away, but not before telling her that he loves her. It also shows Louis, Harvey's long-time rival telling Donna that Harvey "has no idea how lucky he is to have her."

Fans are wondering whether Harvey and Donna will finally get together. Sarah Rafferty, who plays Donna in the series, revealed in an interview that her character is questioning "whether Harvey is a match for her or whether he's ready for what she's looking for," according to The Christian Post.

It also seems like there might still be some more hide-and-seek involved before Harvey and Donna really become a couple. When TV Line asked Suits executive producer Aaron Korsh about what kind of fallout fans can expect from Harvey's confession, he replied:

"Well, I will say I don't view it as Harvey's confession. Different people are viewing it in different ways. There was a moment they might have slept together. They had a moment in there. Nothing happened. Donna says, "Why?" Harvey says, "You know why," meaning he doesn't want to take it to that other level. Harvey was jealous of Stephen, and he said, "Just because I don't want a relationship with you doesn't mean I can't be jealous of another guy with you." So Harvey wasn't confessing his deep-seeded love to Donna, in my opinion."

Check out the finale episode's official synopsis below:

"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."

Suits season 4, episode 16 Not Just A Pretty Face airs tonight, 4 March at 9pm ET/PT on USA Network.
