Also, one of the most popular "Grey's Anatomy" stars is going to direct for the first time.

"Grey's Anatomy" Season 14 has been fantastic so far, and we're excited for what's ahead. You may have seen that at some point there will be an episode showing Dr. Alex Karev's childhood. Now actress Jessica Capshaw has our hopes up for an episode focused on her character, Dr. Arizona Robbins, directed by none other than Jesse Williams (Dr. Jackson Avery).

Here's how that conversation played out:

Jessica Capshaw also re-tweeted this fan reply:

Was she serious or joking? It could go either way. TVLine did a story on Arizona's episode, but shared no new details or confirmation from ABC. It could've been a joke. Then again, she hasn't denied it, or tweeted to clarify that she was kidding. So ... can we officially celebrate?

GREYS ANATOMY - "Harder, Better, Faster, Stronger" - April is in charge of the new Grey Sloan Surgical Innovation Contest, and the doctors are eager to start their projects. Meanwhile, Catherine's old friend has a shocking idea for Catherine and Jackson; and Meredith treats a returning patient who inspires her project, on "Grey's Anatomy," THURSDAY, FEB. 8 (8:00-9:00 p.m. EST), on The ABC Television Network. (ABC/Mitch Haaseth)JESSE WILLIAMSIt didn't sound at all like a joke that Jesse Williams will direct, and it would be his first credit. Kevin McKidd (Dr. Owen Hunt) and Debbie Allen (Dr. Catherine Avery) direct all the time, and Ellen Pompeo (Dr. Meredith Grey) has been directing more since her first time last season. It's great that more cast members are stepping into the ring.

If an Arizona standalone happens, it could show flashbacks of her past, as they are reportedly doing for Alex. Or they could keep it in real-time with Arizona, maybe Sofia, and her relationship with DeLuca's sister Carina. There's certainly plenty of material. As co-showrunner Krista Vernoff told TVLine, there's more ahead on the Carina/Arizona front:

"Carina's not over Arizona. People have commitment issues in the world and Arizona happens to be one of those people. And Carina also happens to be one of those people. And there's a lot of fun to be had looking at that down the line. But don't think for a minute that love story is over."

Also, make room for Dr. Jo Wilson's past to be explored, too. Here's what Camilla Luddington told TV Guide:

"There is a particular episode that comes up later this season where we do get more of a glimpse into perhaps what Jo's life was like."

Will that happen in Alex's episode? Or maybe Arizona's? Just keep it in mind and stay tuned.

In other "Grey's" news, TVLine also reported that Kim Raver is returning later in Season 14 for "a multi-episode arc" as Dr. Teddy Altman.

Teddy had already returned earlier this season as part of the Owen/Megan/Riggs storyline, then disappeared again. It's not clear what Teddy will be doing when she returns -- presumably something with Owen? -- but TVLine did note that Raver will have to balance "Grey's" with her upcoming role on ABC's "Designated Survivor."

"Grey's Anatomy" Season 14 continues Thursdays at 8 p.m. on ABC. By the way, the photos of Jackson and Arizona/Carina above are from Episode 12, "Harder, Better, Faster, Stronger," which airs February 8.
