This Thursday's episode of Grey's Anatomy is going to be unique, as it will focus mainly on just four characters – Meredith, Stephanie, Richard and Owen – as they try to save a patient and all the drama will be confined to the OR.

The episode is titled The Room Where It Happens, and it will see Richard teaching some new techniques to his fellow colleagues as they operate on a badly injured patient. Richard will encourage the doctors to form a connection with the patient and it will result in them recollecting several sad moments from their past.

For instance, Meredith will think back to the day she lost Derek and Owen will recall an interaction with his sister Meghan. For Stephanie, it is growing up with chronic illness. As for Richard, it is rumoured that viewers will get to see a bit about his years as a young boy.

"Everybody in that place has ghosts," actress Jerrika Hinton, who plays Stephanie, told TVGuide. "Every surgeon there has ghosts that inform the way that they practice. What you find out with Stephanie is that her ghost isn't a separate person, it's not a separate entity. It's her. It's this other version of her, and I think that's a bit unique. It makes her challenges, the things that drive her, a bit more complex and a bit more nuanced, perhaps, than she's been given credit for."

Hinton also added that viewers will see a side of Stephanie's that hasn't been on display before. "She has this burst of insight into what's likely happening, and her superiors aren't willing to hear this," Hinton says. "So, she has to fight for this patient. This is kind of a story beat that we're used to seeing in every episode, right? That the surgeon has this amazing realization and then has to go in and fight for this patient, against all odds. But she's also fighting for this younger version of herself."

Grey's Anatomy airs Thursdays at 8 pm ET on ABC.
