"Suits" season 4, episode 9 spoilers reveal that Louis might make the ultimate sacrifice for his betrayal in order to exonerate Harvey and Mike, as the SEC continues its investigation.

The teaser trailer released by USA Network provided some "Suits" season 4, episode 9 spoilers, as Harvey confronts Louis for his colossal mistake.

"You have to put the firm in jeopardy all because you wanted to be the hero?"

"I had no choice!" Louis barks back.

Jessica is about ready to lay down the hammer when she said that "his actions threaten the whole firm." She's probably talking about Louis, but she could quite possibly be talking about Mike whom she doesn't like the moment he returned to the firm.

It must be remembered that Louis in the last episode tried to bury his mistakes, literally, when he hid the Forstman document in the storage files of the firm. Sam Cahill then presented a search warrant to procure any information relating to Gillis Industries.

A miffed Jessica said that Sam Cahill is welcome to search all the documents all the way back to 30 years, which would unwittingly reveal the Forstman document. However, a judge quashed the search warrant so the firm lived to see another day.

Harvey sent his attack dog, Mike, to try to find a way to stop Sam Cahill from continuing the investigation.

Sean Cahill, meanwhile, demanded that all communication between Harvey and Mike be released but unfortunately, the documents included the one from Forstman that Louis tried desperately to bury.

According to HollywoodHills, "Suits" sesason 4, episode 9 spoilers showed that Louis will make the ultimate sacrifice in order to save the firm in the episode entitled "Done."

But will it be enough for a vengeful Sam Cahill to stop snooping around for Pearson & Specter's secrets?

"Suits" season 4, episode 9 will air on Wednesday, August 13 at 9 p.m. on USA Network.
