"Suits" season 4, episode 10 spoilers reveal Harvey and Mike going head-to-head again, while the summer finale welcomes recurring characters as the show prepares for season 5.

According to the official "Suits" season 4, episode 10 spoilers released by USA Network: "Harvey and Jessica take measures to protect the firm from an outsider trying to poach their clients, and Louis struggles to get his personal and professional affairs in order."

More "Suits" season 4, episode 10 spoilers can be gleaned from the teaser preview uploaded on YouTube. The 20-second clip shows a major breakdown in the firm as Mike seems to have done something that will turn everybody's lives upside down.

A very angry Harvey is then seen confronting Mike at the end of the teaser, "What did you do?"

Meanwhile, creator Aaron Korsh dished out "Suits" season 4, episode 10 spoilers on his official Twitter account. The key points were culled and published on the Cartermatt website, and among the highlights include the appearance of "more than one recurring character" in the finale.

He also said that what happens in the summer finale will have long-term impacts on the major characters in the show.

Although Harvey's brother will figure out into the show's plot, he probably won't be seen in the final episode.

"The same goes for seeing Scottie, who Korsh clearly wants to have on the show again if possible. Abigail Spencer's a busy woman! We suppose it's possible she returns next week, but it'd definitely be a shocker..." Cartermatt said.

The writers and producers will then prepare the next episodes to signal the start of the second half of the season, after which Aaron Korsh and his team will gear up for the fifth season of "Suits."

Earlier, CinemaBlend reported that "Suits" was renewed for the fifth season according to USA Network president Chris McCumber who said that the series "continues to fire on all cylinders, averaging 1.6 million viewers in the coveted 18-49 demographic."
