Days away from the Season 13 premiere of "Grey's Anatomy," ABC teased fans on what's next on the medical drama series with all the recent promotional video materials.

Heading to its 13th season, "Grey's Anatomy" will be focusing on the topic of domestic violence.

According to Entertainment Weekly, season 13 will pick up the aftermath of Alex (Justin Chambers) pummeling DeLuca (Giacomo Gianniotti) following what was ultimately a miscommunication resulting from Jo's revelation.

To recall, both have dealt with domestic violence in different capacities during their lifetimes and the drama series writer, Shonda Rhimes, is reported to explore those stories in depth. Moreover, Rhimes explained she never set out to tackle heavy issues, but she feel that it is important to explore such things as they pertain to her characters.

"I don't think that I ever think about doing things, like, 'Oh, we're doing a domestic violence story as an issue," Rhimes said.

"It felt like it was time to tell Jo's story, and it felt like it was time to tell Jo's story especially in the context of Alex, who he is and how he grew up. Alex is so defined by who he used to be and who is trying to become, and so is Jo," she added.

Rhimes added that the storylune is part and parcel of "Grey's Anatomy" putting focus on the remaining original characters including Alex, Meredith, Webber and Bailey.

"Meredith will always be the nucleus because she's the voice, but to have the four originals still is pretty amazing," Justin Chambers said during an interview.

"After such a long period of time and so many new people coming in and out, they remain the foundational characters of the show," Kelly McCreary said. "We're gonna be spending some more time with them to check in with where they are. The way that we spent time with Meredith last season, exploring the major shift in her life, the loss of Derek, I think we can expect to see those doctors being explored where they are in this moment, all these years later, the changes that they've gone through."

The revealed storyline is reported to be several years in the making, according to Rhimes.

"That concept is something that we've - the writers - have talked about for years, and have always been like, 'Is this the right time? Is this the right time?'" Rhimes said.

"We've been trying to figure out when to deploy that. It felt right at this moment in time because Jo's backstory has always been very intriguing to us, and this idea that she is now fully who she says she is, and that she is somebody who has reinvented herself," she added.

Moreover, she revealed that Jo's husband may appear on this season and viewers may get to meet him soon.

"This idea that women are often treated in this way is disturbing to me, but it's also very interesting to me to get to tell the story of Jo from this perspective of somebody who has walked away from a past that happened so long ago, and might have to face it again," she revealed.

"Grey's Anatomy" returns on September 22, Thursday at 8 p.m. EDT on ABC.
