Tonight on Suits, Harvey tries to convince a judge that a drunk man betting his company on a game of poker is not legit. But how could he not be? He wrote it on a napkin! The winner of this game wants what is contractually owed to him. Harvey and Mike try to show that the man was wasted at the time and wasn't thinking logically. But the judge rules the case to go to trial. To make matters worse, the man will lose his company in the meantime.
While on the case, they find out the director has been stealing from his own company, which causes Louis to be down in the dumps. But Rachel gives a convincing you-don't-put-up-with-crap speech to Louis, who is then motivated to rework the company's finances and fire the director -- and all is good.
Rachel has proven her worth to Louis. It's worth mentioning that when she was helping out, she got all her work done overnight, prompting him to fire his associate and replace him with Rachel. Even though she's "just" a paralegal, she's outperforming others above her. This is something to keep an eye on moving forward. Will she continue to keep taking on cases like she had here? Will Louis want to work with her again? I don't see why not, although I'm not sure if she would be as eager to from now on, now that she knows what Louis had been up to.
After the case, Louis shows Rachel his trust in her by giving her his tape recorder. And this is where I hate Louis again, and where Rachel might start rethinking whatever respect she gained for him: The ever curious Mike sees the recorder and hits play, and he and Rachel come across a private chat between he and Harvey. Mike at first, doesn't tell Harvey about it, and then gives up the recorder. Harvey takes it -- for safe keeping.
