War has been declared at Grey Sloan Memorial Hospital in "Grey's Anatomy" Season 13.

Episode 13, "It Only Gets Much Worse," -- airing Thursday, Feb. 16 -- appears to follow the progress of Dr. Eliza Minnick (Marika Dominczyk) as she attempts to push out Dr. Richard Webber (James Pickens Jr.). ABC's synopsis also suggests we'll follow Dr. April Kepner (Sarah Drew) in her "new role at the hospital."

ABC shared some photos for Episode 13, and they focus on Eliza, her love interest Dr. Arizona Robbins (Jessica Capshaw), Dr. Stephanie Edwards (Jerrika Hinton), Dr. Leah Murphy (Tessa Ferrer), Dr. Owen Hunt (Kevin McKidd), Dr. Jackson Avery (Jesse Williams), and a young patient and his family. For whatever reason, there are no photos of April, never mind Dr. Meredith Grey (Ellen Pompeo), Dr. Alex Karev (Justin Chambers), or Dr. Jo Wilson (Camilla Luddington), who are not mentioned in the synopsis at all. And Dr. Amelia Shepherd (Caterina Scorsone) still appears to be missing. (Poor Owen.)

Here's the official synopsis for "It Only Gets Much Worse":

The residents are excited for Eliza's next phase of teaching, but they spend the day caught between the warring attendings. Meanwhile, April has a challenging first day in her new role at the hospital.

Here are more of the promo photos, beyond the one above of Eliza and Arizona:

This Thursday's (Feb. 2) Episode 11, "Jukebox Hero," follows Meredith's attempt to track down Alex. Then we have Episode 12, "None of Your Business," which will introduce Maggie's mom and drag Stephanie into Owen and Amelia's drama.

Speaking of Stephanie, after it was announced that actress Jerrika Hinton was joining Alan Ball's new HBO drama, we assumed that meant bye-bye for Dr. Edwards. TVLine confirmed that Hinton will not be a series regular in Season 14, but they did not have details on what would happen to the character of Stephanie, or if she'll still be back for guest appearances.

"Grey's Anatomy" Season 13 airs Thursdays at 8 p.m. on ABC.
