'Suits' Season Finale Spoilers: Donna Confronts Harvey about His Love for Her in 'Not Just a Pretty Face'

'Suits' left fans with one major cliffhanger after season 4 episode 15 'Intent', when Harvey (Gabriel Macht) admitted to his secretary and confidante Donna (Sarah Rafferty), that he loves her. 'Suits' fans have been rooting for the two of them to get together for four years and on episode 16 'Not Just a Pretty Face', which also marks the season finale, it looks like Donna will finally confront Harvey about his feelings for her.

SEC investigator Sean Cahill (Neal McDonough) will make a comeback to "Suits", seeking Harvey's help in linking his corrupt boss Eric Woodall (Željko Ivanek) and corporate raider Charles Forstman (Eric Roberts). Woodall, who is a sworn enemy of Harvey, had once tried to go after him using Mike (Patrick J. Adams) and was fired from the US attorney's office as a result. He was then given the post at SEC by Frostman, a corrupt billionaire investor, and in return Woodall protects him legally. 

Harvey is forced to revisit some of these uncomfortable past, to bring the duo down. Possibly because it is a tough call for him, Jessica is seen telling Harvey, "Don't say I didn't warn you."

Meanwhile, Rachel (Meghan Markle) and Mike go through a rough patch as they discuss the fact that Harvey still goes to Mike for everything, although Rachel is his associate. Over the course of the last four years of "Suits", it has been displayed time and again that Harvey considers Mike as his go-to guy and that he has a big brotherly love for him. It was only a matter of time before Rachel realises that no matter how hard she tries, Mike would always be the first person Harvey turns to, when he needs legal assistance.

Louis (Rick Hoffman), who was understandably offended after Donna chose Harvey to handle her "criminal intent" case in 'Intent', needs to placated. Donna is possibly helping him out in the Season finale to earn back his friendship. She is among the few people that Louis truly loves and he constantly compares her to his own secretary Norma.

He told Donna in the last episode that "Harvey has no idea how lucky he is to have you" and according to the trailer for episode 16, says it again. He is possibly reinstating that while Donna is a great secretary and friend to Harvey, he sometimes takes her for granted. 

Harvey could be scared of ruining that perfect friendship they share, which is why he is hesitant of pursuing a romantic relationship with her. The only time the two of them spent the night together, just before they joined  "Gordon Schmidt Van Dyke" - now, "Pearson Specter Litt"- they had also decided that if they were to engage in a professional relationship, a romantic one is out of the picture.

However, with episode 15, it is pretty clear that both of them have hidden feelings for each other, and once it is brought to the limelight, "nothing will ever be the same", as the show runners are promising. Nevertheless, their feelings for each other will definitely be discussed, because in the trailer, Donna is seen telling Harvey, "You ran away.. but not before you told me you loved me".
