'Grey's Anatomy' season 13 episode 15 spoilers, news: Meredith finally gives Nathan a chance; what will happen to Amelia and Owen?

When season 13 of "Grey's Anatomy" returns, Meredith (Ellen Pompeo) will finally give Nathan Riggs (Martin Henderson) a chance. Meanwhile, the decision regarding Amelia (Caterina Scorsone) and Owen's (Kevin McKidd) marriage will be unveiled.

"Grey's Anatomy" season 13 is currently on a two-week break, but when it returns with episode 15, titled "Civil War," Meredith will be establishing ground rules with Nathan for him to have a chance of building a relationship with her.

As seen from the episode promo, Nathan will try to get Meredith to admit that he actually has a shot with her. However, things might get complicated for Meredith as Alex (Justin Chambers) will soon have a problem with Dr. Riggs.

"Amelia finally faces her feelings about Owen, and Meredith gets caught between Nathan and Alex over a patient," the listing from The Futon Critic reads.

Meredith won't be the only one having a complicated situation, as Amelia will finally come to Owen to talk about her feelings.

In a previous interview with Variety, McKidd shared that he wishes for his character to finally find someone who can fulfill his dreams of having a family.

"I wish and pray for Owen that he will one day get that child, and be with someone that wants to have that child with him, and I hope that person is Amelia," Kidd revealed.

There might be a possibility that Amelia will never get over the trauma that she has with having a child, leaving Owen no choice but to break off their marriage.

"Eventually Owen is going to have to say he can only do this so many times and he can't do it anymore," McKidd added.

The hospital will also find two married couples — Richard (James Pickens Jr.) and Catherine (Debbie Allen), and Jackson (Jesse Williams) and April (Sarah Drew) — at war over deciding on a priority case.

"Grey's Anatomy" season 13 returns on March 9 at 8 p.m. ET on ABC.
