Wait … who’s your daddy? That’s the question “Devious Maids” fans were asking themselves after the hit Lifetime series aired episode 7, titled “Blood, Sweat And Smears.”

In the Season 4 installment, fans take another step closer to finding out why Frances (Stephanie Faracy) believes that Tucker (Carter Birchwell) is “the key to everything” — and it has to do with the boy’s blood. During episode 7, Rosie (Dania Ramirez) witnesses Spence (Grant Show) and Peri’s (Mariana Klaveno) son collapse on top of his toys, forcing her stepson to be brought to the hospital.

“Apparently he had some internal injuries from the car crash,” Tucker’s Aunt Shannon (Kathryn LaNasa) reveals, adding that Tucker has a heart injury that needs to be surgically fixed. But the operation will have to take place in a few days, Shannon continues to tell Rosie, elaborating that due to Tucker’s rare blood type, it’ll be hard to find a match. Rosie suggests that they use Spence’s blood but Shannon quickly dismisses the idea.

“Maybe she’s taking orders from the circle,” Rosie theorizes why Shannon doesn’t want to use Spence’s blood during her prison visit with her husband.

After Spence returns to his cell, the helpless father complains to his fellow inmate about not being able to come to his son’s rescue. Kill Face (Owen Harn) then comes up with a plan: If Spence wants to give blood to his son, he needs to get into the hospital where Tucker is staying. And what better way to get Spence in a hospital than by stabbing him with a shiv?

Kill Face jabs his homemade weapon into Spence’s derriere, causing the injured prisoner to be rushed to the hospital. But Rosie finds out from a nurse that the blood Spence donated during his stay wasn’t used during Tucker’s surgery. According to the nurse, Spence has a blood type AB while Tucker has the rare blood type of O negative.

“Are you saying Spence isn’t Tucker’s father?” Rosie asks the nurse who reveals Spence’s blood wasn’t a match.

“You didn’t hear that from me,” the nurse responds. So who is Tucker’s father? Well, we think Aunt Shannon may know more than she’s letting on.

While Rosie unravels Tucker’s mysterious family tree, Evelyn (Rebecca Wisocky) sought out legal counsel, thanks to Adrian’s (Tom Irwin) generous charity donation, in the dreaded Valley. Hey lawyer advises the socialite that if she wants to maximize the money she gets from the divorce settlement that she’ll need to move back into her mansion … and fast!

So, Evelyn enlists in the help of Carmen (Roselyn Sanchez) to get back into her home — for a small fee, of course. After the price is paid, Carmen lets her former employer know when Adrian is out, enabling Evelyn and her new beau to slip into the estate.

But Carmen herself could use some backup herself from her creepy, new boyfriend. After having a mind-blowing night with the barista, Carmen notices something strange on his computer — a folder full of photos … of her! Some images are of the aspiring actress sleeping while others are of Carmen with her head photo shopped off.

After Carmen musters up the courage to confront the barista, he explains he was trying to make cover art for her impending album, titled “Dreams” (thus the sleeping pictures!). Carmen’s thrilled to hear he’s not psychotic but decides to end their relationship anyway. However, unfortunately for Carmen, her coffee-pouring beau is quite the revenge seeker. After getting dumped, he calls Daniela (Sol Rodriguez) to give her Intel on her birth father — information Carmen didn’t want her daughter getting her hands on.

While one relationship falls apart in episode 7 of “Devious Maids,” another is mended. After a nearly a season of feuding, Zoila (Judy Reyes) and Genevieve (Susan Lucci) patch up their relationship thanks to a little help from Adrian. He helps Zoila realize that she’s using Genevieve as a scapegoat for the death of her child.

“I needed someone to blame. I am so sorry it took me so long to see that,” Zoila says to her former employer, ending their fight once and for all.
