Marisol (Ana Ortiz) could find herself on the wrong side of Olivia's (Valerie Mahaffey) wrath after she continues to investigate her possible role in Louis and Blanca's (Naya Rivera) murders on Devious Maids.

Olivia Returns

In a preview clip for the Monday, August 10 episode, she will try to warn Michael (Brett Cullen) of Olivia's confession that she set Taylor (Brianna Brown) up for a failed marriage with a devious plot-something Michael won't take too kindly to hearing at first.

"Olivia...she's up to something," Marisol warns in the clip.

"You're going to regret saying that," he replies.

However, as more evidence begins to mount against her, Michael will quickly realize that Olivia's as crazy as she was a few years ago-and still very much obsessed with him, which will cause him to lash out at her for trying to find a twisted way to get him back.

"You need help," Michael says in the clip. "Get this through your sick, twisted brain, I will never come back to you, ever."

Olivia will realize that Marisol sold her out and is the one who got Michael to see the negative qualities in her again however-and as a result, she will head to the former maid's home to make sure she pays the ultimate price for her betrayal.

"Such a same when friendships have to end," Olivia says to Marisol as she pulls out a knife.
