Grey's Anatomy Season 9 will premiere in less than a month's time. Creator Shonda Rhimes teases avid viewers with a "surprising reaction" from Meredith, and some "expected-and-unexpected" reactions from Cristina.

Meredith Grey as Mercy West Nazi?

Ellen Pompeo has spoken a little bit more about her character's "surprising reaction."

Speaking to Wetpaint.com, Pompeo said her character will resort to anger to cope to what she has gone through post-plane crash.

"She's angry about all the stuff that happened, so she's teaching her interns and she's really mean to them. It's an homage to the first Dr. Grey, Meredith's mother, who is the first bitch surgeon, so I get to channel Kate Burton [Ellis Grey, Meredith's mother] and be mean," she said.

Cristina Yang 'resets' relationship with Owen Hunt

Meredith's person, Cristina Yang, also has a lot of coping up to do after the tragedy that made her watch her best friend's sister die.

Yang has said she has learned one thing in "Mercy West Mercy Death," and that is she is "not interested" in dying. What were her thoughts about her husband Owen Hunt (Kevin McKidd) when all the death and near-death drama was unfolding before her eyes?

Shonda Rhimes told The Hollywood Reporter that Cristina is going to deal with the tragedy in her own way. She will exhibit reactions that are "both expected and unexpected" for fans who have grown to know - and love - her character's tough persona.

Rhimes said Grey's viewers are "going to really follow" Cristina next season.

As for McKidd, he told Belfast Telegraph that his character's wife will go through a "reset" of some sort.

"(T)he plane crash is pretty much going to press a big reset button on Cristina and Owen's priorities so it'll be interesting to see where they are at emotionally for each other when we start the next season," he said.

An entire episode on Meredith and Cristina

Rhimes also teased the viewers on an exclusive Meredith-and-Cristina episode next season. She hinted this particular episode will be extraordinary for two of the central characters of the series.

"It's not a regular episode. I won't be able to explain what the gimmick is until I've seen it shot and we've decided on the visual style of it. But it is going to be fairly different," she told TV Line.

"I don't think we've ever told a story the way we're telling a story in this episode," the series creator noted.

Grey's Anatomy Season 9 will air its premiere in September.
