ABC confirmed Walsh will come back as Addison in Grey’s Anatomy Season 18 Episode 3, which is titled “Hotter Than Hell.” The new episode will debut on Thursday, Oct. 14, and Addison will help Richard Webber (James Pickens Jr.) tease the newest Grey Sloan Memorial residents with her impeccable skills. 

Meanwhile, Walsh will be back for at least a few episodes. ABC revealed Addison will also return in episode 4 of Grey’s Anatomy Season 18, titled “With a Little Help From My Friends.” 

In the Oct. 21 episode, Addison’s patient will have some “complications” from a previous procedure. Could this be the transplant patient that Addison and Meredith Grey (Ellen Pompeo) will operate on in episode 3? We’ll just have to wait and see.

We already know Meredith and Jo will interact with Addison in Grey’s Anatomy Season 18. As mentioned, Meredith and Addison will work together in episode 3. Cast member Camilla Luddington (who plays Jo Wilson) also revealed that her character will try to get on one of Addison’s cases. 

That said, many Grey’s Anatomy fan theories surrounding Addison’s return seemed to revolve around Amelia, given their Private Practice history. So will Walsh and Scorsone get to act together soon? According to TV Insider, Walsh told TV Guide Magazine that Addison and Amelia will get “beautiful, intimate scenes” in season 18.

Of course, we’re not surprised Amelia and Addison’s reunion in Grey’s Anatomy Season 18 will be emotional. So what can viewers expect from the conversation? Previously, a few fans predicted that Amelia will be able to talk to Addison about Atticus “Link” Lincoln (Chris Carmack). Then when speaking with TV Guide, Vernoff seemingly confirmed the theory.

The Grey’s Anatomy Season 18 showrunner revealed that Amelia will confide in Addison, telling her former sister-in-law why she really turned down Link’s proposal. Vernoff also shared that the two women will be able to “open up to each other in ways they don’t with anyone else.”

Get those tissues ready, Grey’s Anatomy fans. Addison is coming back in episode 3 of season 18. So the moment we see Amelia and Addison together again, we know it’ll be time for the waterworks to begin. Stay tuned.

Grey’s Anatomy Season 18 airs Thursday nights on ABC.
