With no big baddie to fight in “Suits” season 7 episode 15, the plot will focus on the tense relationships of all the characters, including some trouble between Mike (Patrick J. Adams) and Rachel Zane (Meghan Markle). A preview video of next episode teases some of these moments.

Mike and Rachael are a happy couple at the moment, and there is little that they will get married. However, there are still some doubts and last-minute troubles in their relationship. The preview video posted on YouTube shows Rachael telling her fiancé that she has never stopped to wonder whether they both want the same thing. The trouble seems to be originating from Mike being indecisive, not knowing what he wants in the future.

The big focus of the episode will be on Harvey (Gabriel Macht). The hotshot lawyer will have to choose between Dr Paula (Christina Cole) and Donna (Sarah Rafferty). The video shows Paula giving Harvey an ultimatum; there’s no future for them if he continues to work with Donna.

What will Harvey do? It looks like he will choose Paula over his colleague, but how exactly he will do this remains to be seen. An emotional Donna can be seen asking Harvey to stand by her after she stood by him every single day. However, her appeal doesn’t seem to have the desired effect.

While Louis (Rick Hoffman) isn’t seen in the trailer, the character will also face some relationship troubles. The previous episode explained the backstory involving the quirky lawyer’s trouble in relationships. Louis decided to be a “bad man” and continued with his relationship with a woman who is about to get married to another man. Now, he will face some difficulty in dealing with the rules of this relationship, according to the episode synopsis.
