Showtime drama “Ray Donovan” airs its Season 4 finale on Sunday night, up against the Emmy Awards (where the show is nominated for the performances of stars Liev Schreiber and Jon Voight, in addition to a directing nod for showrunner David Hollander). The show has already scooped one award in this year’s Emmy race, nabbing Guest Actor in a Drama Series for Hank Azaria at last weekend’s Creative Arts Emmys.

The season began with Ray’s burgeoning friendship with professional boxer Hector Campos (Ismael Cruz Cordova), a fellow abuse survivor who had also turned to the church to try and get a fresh start. In a striking turn of events, Hector told Ray about one of his darkest secrets — his incestuous relationship with half-sister Marisol (Lisa Bonet).

After Hector snapped and killed Marisol for publicly revealing their controversial relationship, he asked Ray to solve the mess. However, as Variety’s exclusive sneak peek reveals, Hector also turns to the church for help, disgruntling Ray.

“Hector called me,” Father Romero (Leland Orser) tells Ray in the clip. “He wants to turn back to God.”

“He sure as f–k didn’t call you when he was drowning his sister in a bathtub, did he?” Ray responds. “Didn’t call God then, did he, Father?”

“No, Ray. He called you,” Father Romero says, with a hint of accusation. Ever the fixer, Ray takes it in stride.

The fourth season included guest appearances from Stacy Keach, Diane Ladd, Dabney Coleman, Embeth Davidtz, Ted Levine, Gabriel Mann, Chris Coppola and Billy Lush. 

The Season 4 finale of “Ray Donovan” will air Sunday, Sept. 18 at 9 p.m. on Showtime.
