"Grey's Anatomy" season 13 recently confirmed the official title for its first episode.
Cast member, director and executive producer Debbie Allen shared a photo of the script for "Undo" which she helmed herself.
"Can't wait to share @GreysABC Season 13 Episode 1 with you! Sit tight! #greys #greysanatomy," she wrote.
The title of episode 1 seems to resonate with Jo (Camilla Luddington) and Alex's (Justin Chambers) relationship. Instead of saying "I Do" in the previous season, it seems that couple may end their relationship in season 13.
After all, Jo has been hiding a huge part of her past from her longtime boyfriend. Alex has no idea that Jo was married and that she was involved with a man who physically abused her.
Meanwhile, it was previously confirmed that the first episode for season 13 will center on April Kepner (Sarah Drew) and Jackson Avery's (Jesse Williams) storyline.
The couple previously divorced, but was reunited at the Grey Sloan Memorial Hospital for the arrival of their baby.
On her first filming day, Drew shared a series of photos with her co-stars Allen and Williams while on set.
In other news, the cast of "Grey's Anatomy" season 13 recently attended the Television Critics Association summer press tour.
Photos from the event were shared on the show's official Instagram and Twitter pages.
Some of the attendees included Camilla Luddington, James Pickens Jr., Chandra Wilson and Jason George.
"Grey's Anatomy" season 13 will premiere on ABC on Sept. 22 at 8 p.m. ET.
