Devious Maids season 2 spoilers What will happen in episode 12 of "Devious Maids"? Get the Season 2 scoop on "Proof." Photo: Lifetime/Devious Maids

“Devious Maids” is one episode away from airing its Season 2 finale, which means you know episode 12 will bring the heat when “Proof’ airs Sunday, July 6, at 10 p.m. EDT.

The synopsis for the soap opera suggests Nick will refuse to divulge in his “secret past” when the new episode airs. Things have gotten even more complicated since Dalia’s death: Nick had been hospitalized after a deliberate hit-and-run; Opal hinted that Marisol’s lover is just as devious as she is; and Ethan’s mom committed a shocking suicide at the end of episode 11 when Marisol learned Opal was the one responsible for pushing Dalia off a bridge the night she was found dead. Nick’s refusal to own up to the truth will lead Marisol on a dangerous quest to seek justice. But will she put an end to the mystery of Dalia’s murder?

Zoila will face her own struggles when she’s forced to chose between Javier and Pablo, both of whom she shares strong feelings for. In episode 11 Pablo showed up to Zoila’s house only to have her current beau, Javier, answer the door in nothing but a skimpy bathrobe.

Looks like Spencer isn’t the only actor in “Devious Maids.” Carmen will be playing the role of babysitter to Spence’s son when episode 12 airs. Rosie has convinced Spence that he needs to go to rehab to help with his addiction to alcohol, which means Carmen is in charge.

The remainder of the synopsis for “Proof” teases that Rosie will recruit Linda and Didi to work together to rescue Kenneth and put an end to Reggie’s financial thievery while Valentina tells the police what she knows about Reggie in his crew.

Episode 12 has all the makings for an explosive episode. Series creator Marc Cherry has even used the 2000 play written by David Auburn for inspiration. For those who aren’t familiar with the Pulitzer Prize-winning drama, “Proof” tells the story of Catherine, a daughter of a respectable mathematician and professor, who has just been laid to rest.

Robert, Catherine’s father, had once been a groundbreaking genius but lost respect when he developed a mental illness. After his death, a student of Robert’s sifts through his office to prove his professor’s final days of teaching weren’t a waste. Hal comes across cutting-edge calculations that turn out to actually be Catherine’s. Robert’s daughter then has to prove that the profound proof is belongs to her.
