Station 19 is bringing in a new father figure.

Dermot Mulroney has joined ABC's Grey's Anatomy firefighter spinoff drama, booking a multi-episode arc for the upcoming second season, ET has learned. The 54-year-old seasoned actor will play police officer Ryan Tanner's (Alberto Frezza) father, which will surely add fuel to the fire.

According to the official character description, Ryan's father returns to Seattle, Washington, after an extended leave -- much to the surprise of pretty much everyone who has ever known him. Described as "sharp-witted, very perceptive and wickedly smart," he can charm his way into and out of almost any situation. He hasn't always been on the right side of the law, which really affects him, especially in the eyes of his son, Ryan.

In the first season, Ryan has made passing references to his troubled childhood, though never explicitly mentioning his parents. With his father back in his orbit, the fraught familial tension he alluded to will be ripe for drama.

Mulroney is just the latest major addition to the season two cast, coming on the heels of Code Black star Boris Kodjoe joining the show as a recurring guest star playing a veteran firefighter with a mysterious past. The ensemble is led by Jaina Lee Ortiz, Jason George, Miguel Sandoval, Grey Damon, Jay Hayden, Frezza, Danielle Savre, Okriete Onaodowan and Barrett Doss.

In January, showrunner Stacy McKee explained how Station 19 is different from its mothership series, the long-running medical hit, Grey's Anatomy. 

“It was a priority for me in thinking of this as a Grey’s Anatomy spinoff that it works hand in hand with Grey’s in tone and intensity and humor and heart. But there’s also the added element to this show that the hospital setting doesn’t allow,” she explained, “which is a lot of our characters on-site. They’re in the middle of action sequences, so there’s a certain level of adrenaline and energy that comes with that that you don’t necessarily find in the same way as Grey’s -- you find it in different ways. It’s very similar in tone and spirit, but also a little bit different as well."

Station 19 premieres Thursday, Oct. 4 at 9 p.m. ET/PT on ABC.
