Watch Levi Confront His Family About His Relationship on 'Grey's Anatomy' Season 16: Spoiler Alert

They say blood is thicker than water, but sometimes it's the people we choose to keep in our lives that feel more like family than friends. Such may be the case for Dr. Levi Schmitt on the upcoming episode of Grey's Anatomy.

The Grey Sloan Memorial Hospital surgical resident, played by Jake Borelli, will have a major story arc Thursday night on Season 16, episode 12, titled "The Last Supper"—and his family, as well as his blossoming romance with boyfriend and colleague Dr. Nico Kim (Alex Landi) will play a big role to his developing storyline as he makes the decision to come out to the rest of his family.

Back on the Season 15 finale, Levi revealed his relationship with Nico—the first gay male relationship ever depicted on Grey's—to his mother. Things will become complicated after he makes arrangements to visit his dying uncle and decides to tell the rest of his family about Nico.

"Out of Levi's whole family, he's had the best relationship with his Uncle Saul. Now that he's out and proud and growing in his own confidence, he decides this would be a good time to introduce his uncle to Nico," Borelli revealed in an interview with TVLine released Wednesday. "Uncle Saul's reaction sort of shocks him. We get to explore Levi coming out to other family members and how the rest of them react."

Levi will also learn his mother isn't as accepting of his sexuality as she made him believe when he first came out to her. "We saw a little bit of his mom's reaction to it, but now we're starting to see behind the veil," Borelli said.

"His mom is sort of ok with [his sexual orientation], but she doesn't want to talk about it with the rest of the family, and she doesn't want it outside of the basement [in her house where he lives]," he continued. "In her own way, she's kept him in the closet."

Troubles with family won't only plague Levi on episode 12.

Dr. Maggie Pierce (Kelly McCreary) and Dr. Jackson Avery (Jesse Williams) will also find themselves in the hot seat when they're parents invite them over for what they believe is going to be an anniversary dinner. However, Dr. Richard Webber (James Pickens Jr.) and Dr. Catherine Avery (Debbie) have something more shocking up their sleeves.

From the looks of the episode sneak peek, the drama is likely only to going to intensify when Jackson invites his girlfriend and Station 19 firefighter Victoria "Vic" Hughes (Barrett Doss), who unexpectedly brings her colleague Dean Miller (Okieriete Onaodowan).

Grey's Anatomy airs on ABC on Thursday at 9 p.m. ET.
