Can Rachel (Meghan Markle) and Mike (Patrick J. Adams) withstand the biggest test of their relationship in the upcoming episode of "Suits" season 5?

Back in the mid-season finale, fans of the show learned that Mike was planning to correct his past mistakes when he faked his educational credentials to land a job as a lawyer at the Pearson Specter Litt law office. This time, he was planning to resign from his post to start a new life with Rachel. However, somebody turned him in, which led to his arrest for fraud.

Series creator Aaron Korsh earlier revealed that viewers of the show will find out the implication of Mike's arrest as well as the identity of the person who divulged his secret.

Speculations revealed that one of Rachel's parents has something to do with Mike's arrest. It could either be her powerful father Robert Zane (Wendell Pierce), or her mother Laura (Megan Gallagher), who went to the police to tell them about Mike's crime.

But while the question about who turned Mike in is still a mystery, fans would also like to find out if the engaged couple will still continue with their wedding plans after Mike's release from prison, or if Rachel will succumb to her parent's whims and marry the guy they chose for her.

Korsh also revealed that Donna (Sarah Lafferty) was really telling the truth to Harvey (Gabriel Macht) that she was seeing someone else. "Yes, she was telling the truth. But it remains to be seen how important that relationship ends up being. She was not lying. I do not think Donna would do that. But it's possible that, since then, they've broken up. We don't know. We have to figure that out," the series creator told TVLine.

The return of "Suits" for the second half of season 5 is slated to happen early next year.
