"Grey's Anatomy" often feels like high school, and never more so than in this new sneak peek from Season 13, Episode 6, "Roar."

As you know, fired doctor Leah Murphy (Tessa Ferrer) is returning to Grey Sloan, and she'll make her debut this Thursday, October 27 on the ABC show. Fans were surprised to see Leah was coming back, but that's nothing compared to her fellow docs.

Leah is the No. 1 source of cafeteria gossip in the new sneak peek clip, with Arizona and Karev -- who both slept with Leah -- wondering how she could come back, as Maggie -- who never knew her -- compliments the "new" doctor's suture techniques. Stephanie, Jo, and DeLuca also discuss Leah's return at another table -- and Leah walks in, lunch tray in hand, just in time to catch Steph dissing her. Awkward!
