"Anything is possible as siblings that care very much for each other," he told TV Line. "But that happens in life, where people who are friends become lovers. Personally, I don't see that [happening] right now. I think it would be kind of strange. I think they're too close... too much like brother and sister. I have super-close friends who I'm not romantically attracted to at all. So I think just because you're so in love with someone in one way doesn't mean it's a romantic love. But they certainly do understand each other a lot," Chambers added.

The official synopsis for the episode reads: Maggie gets a surprise visit from her mother at the hospital. Bailey has to make a difficult decision when one of the attendings refuses to work with Eliza, and Stephanie gets caught up in Owen and Amelia's personal drama.

Meanwhile, the Grey Sloan Memorial has become a battlefield due to the ongoing war between Richard Webber, Miranda Bailey, and new chief of the hospital Eliza Minnick. In a promo released by ABC, April becomes curious after seeing Webber's wife Catherine Avery in town asks her if she is going to put a halt to the ongoing battle between the doctors.

"You should keep your mind on the scan and not on my marriage" warns the veteran doctor.
