'Suits' Season 5 Spoilers: Daniel Hardman And Louis' Sister Esther Return In Episode 7 [VIDEO]

Pearson Specter Litt (P.S.L.) has two familiar visitors in this week's episode of "Suits."

The promo for the show's season 5 episode 7, entitled "Hitting Home," reveals that Daniel Hardman (David Costabile) is returning to the firm.

"Jessica (Gina Torres), what a pleasant surprise?" Daniel greets Jessica.

To which Jessica replies, "Oh, I think we both know that it's not."

It's unclear why Daniel is meeting up with Jessica, but it seems likely that Daniel is back to get revenge.

After getting dismissed from Pearson Hardman for fraudulently suing the company back in season 2, Daniel started to file several cases against the firm. And although the lawsuits held no weight, Daniel knew that either Jessica or Harvey (Gabriel Macht) would have to settle the cases or go to court and fight them all off, both bankrupting the firm in the process. Jessica then merged with Darby International to create Pearson Darby, and with Darby's funds they managed to get rid of every case Daniel had against them.

Meanwhile, according to the synopsis for the episode, Louis' (Rick Hoffman) sister, Esther (Amy Acker), also returns to P.S.L. "to solve a problem discreetly." But since "Louis rarely handles anything quietly, especially when it comes to family," the siblings, as seen in the promo, end up with a yelling match.

"I'm not your buffoon brother," Louis told his sister.

To which Esther replies, "You make everything worse."

The synopsis didn't specify Esther's problem, but based in the promo, it seems that it has something to do with Harvey. In the final seconds of the promo, Louis reminds Harvey of a promise he made. Harvey then warns him to watch his words, but Louis goes on to tell him something, causing Harvey to seemingly slap him.

Elsewhere in the episode, Jessica asks Mike (Patrick J. Adams) to team up with Jack Soloff (John Pyper-Ferguson) to co-counsel a case, and despite their history the two come to a surprising understanding.

In addition, Donna (Sarah Rafferty) and Harvey try to get their friendship back to normal, but Harvey has a hard time stomaching Donna's "friendly advice."

"Suits" season 5 episode 7, "Hitting Home," airs on Wednesday, Aug. 5 at 9 p.m. on USA Network.
