Grey’s Anatomy isn’t done with Addison Montgomery, and Addison Montgomery isn’t done with Grey’s Anatomy.

　　First introduced in the season-one finale as Derek Shepherd’s estranged wife—and therefore Meredith Grey’s antagonist—the neonatal surgeon played by Kate Walsh gained enough popularity for her own spin-off, Private Practice, and has returned to Grey’s a handful of times since, including earlier this season. (Offscreen, Walsh and series star Ellen Pompeo aren’t rivals but friends!)

　　And she’s coming back! Walsh announced the news on Twitter, posting a video of herself doing a trend that’s popular on TikTok: Set to a clip from SpongeBob Squarepants, someone enters, exits, and reenters “in uniform.” (Here’s a compilation if you want to kill seven minutes and several brain cells.) For hers, Walsh changed from loungewear to a cocktail dress, heels, and a doctor’s coat. Okay, close, but shouldn’t she be wearing scrubs? “I’m back in uniform and that can only mean one thing… #GreysAnatomy Stay tuned @GreysABC,” she wrote.

　　When Kate Walsh announced she was returning to Grey’s Anatomy in its 18th season, she was confirmed for “multiple episodes,” but an exact number was never divulged. My guess is that Addison’s time in Seattle is not over. While this pregnancy failed — as important as it was to the patient — the transplanted uterus was able to be saved, so I think Addison’s got more work to do.

　　Also, there are only two episodes remaining before the Season 18 finale — and it’s a big one, as the finale also marks the medical drama’s 400th episode. It would be quite a shame to invite Kate Walsh back on the show after all this time and then have her character leave so close to such a milestone.

　　The show needs her anyway. Many times during “Should I Stay or Should I Go,” Addison was the lone voice of reason, as Richard continuously made snide remarks about loyalty and even reminisced about the days of teaching Addison and Derek (low blow, Richard!).

　　The seemingly unflappable Catherine showed her own frustrations in the most unprofessional way, as she stormed into the O.R. following Addison’s tough surgery and laid into Meredith for her decision to leave. Addison even got caught in the crossfire before loudly — and rightly — reminding everyone of the patient near them who had suffered real loss.

　　Meredith in the end decided to stay in Seattle — for now — because she could never really leave her hospital family in the lurch like that. Hopefully Grey’s Anatomy will allow Addison to make the same choice.

　　Grey’s Anatomy returns next week at 9 p.m. ET on ABC, and it’s all leading up to the two-hour season finale on May 26, which will see the return of Jesse Williams and Sarah Drew as fan-favorites Jackson and April.
