It's been an ugly battle between Harvey and Louis on Suits, but one of them might get some massive revenge.

'Suits' Promo Shows Charles Barkley's Guest Appearance

On Wednesday, a promo was released on next Wednesday's episode when Louis's younger sister, Esther, comes into the office. She's likely going to see Louis for a visit, but she'll also spend time with Harvey- likely to help her with a case.

Based on what the promo shows between the siblings, it sounds like they don't have the greatest family bond. But regardless of that, Louis is still protective of his little sis since he tells Harvey not to sleep with her. Harvey doesn't seem to show any desire that he's into Esther that way although it would be a sneaky way to get vengeance on Louis for their office battle.

Chatter On Harvey's Replacement For Donna On 'Suits'

Harvey and Esther may get along pretty well since he asks her if one of them is adopted. Louis doesn't trust his co-worker with his sibling so he tries to listen in to their conversations. And odds are likely he will have something to worry about as the sexual tension kicks in for Esther and Harvey.

Esther seductively asks the man, "Would you like to take me home tonight?"

Harvey's answer isn't heard, but his smile says it all.

Esther will be played by Angel and Dollhouse actress Amy Acker.

Suits airs on Wednesdays at 9 p.m. ET on USA.
