Kevin McKidd, Kim Raver, Camilla Luddington and Caterina Scorsone, among others, also returned for the new season.

Greg Germann, who has played Dr Tom Koracick on Grey's Anatomy since season 14, will return as a guest star on multiple occasions but his time as a series regular has come to an end.

While earlier this year, Deadline confirmed that Kate Burton would be returning to play Meredith's late mother Ellis Grey, who died in season three, in multiple episodes – however, it's unclear how the character will be reintroduced. She has so far appeared in a dream sequence.

Also returning to the cast in season 18 is Abigail Spencer, who is reprising her role as Dr. Megan Hunt, as well as Kate Walsh, who played fan favourite Dr. Addison Montgomery from 2005 until 2012 on Grey's and its spin-off series Private Practice.

Meanwhile, Scott Speedman, who guest-starred as Nick Marsh in season 14, has joined the cast as a series regular for season 18. In the season premiere, Meredith bumps into Nick Marsh whilst opening a library dedicated to her mother in Minnesota and goes for a drink with him.

The OC star Peter Gallagher joins in a recurring capacity as Dr David Hamilton, Lynn Chen plays new arrival Dr Michelle Lin, and Greg Tarzan Davis plays a new doctor keen to learn from Bailey, Dr Jordan Wright.

Non-binary actor E.R. Fightmaster also portrays Dr Kai Bartley, a non-binary character who becomes a love interest for Amelia.

In the second half of the season, Rome Flynn has also been cast as Wendell Ndugu, the brother of Winston, while Skylar Astin portrays Todd Eames, an environmental sciences expert.

Is Grey's Anatomy ending with season 18?

No, as Grey's Anatomy has been renewed for a season 19.

Ellen Pompeo has been confirmed to be returning as Dr Meredith Grey for another season of the hit medical drama, along with fellow remaining original cast members Chandra Wilson and James Pickens Jr.

The Hollywood Reporter reports that Pompeo received “another salary increase and remains broadcast television’s highest-earning actress in a primetime drama series."

Dana Walden, chairman of entertainment at Walt Disney Television, said: "Grey’s Anatomy is a true phenomenon, beloved by audiences around the world. Whether they catch it live on ABC, or stream it on Hulu or globally on Disney+ or Star+, it’s clear that fans can’t get enough of Shonda Rhimes’ brilliant creation."

They added that they hope the show's storytelling will "resonate deeply with loyal fans for years to come."

So maybe don't expect season 19 to be the last, either!

It is unknown currently when this new appearance will air in the UK.

Richard Flood leaves Grey's Anatomy

Irish surgeon Dr Cormac Hayes has waved goodbye soon after he resigned from his position and departed the hospital - meaning fans hoping for him to find love with Meredith are no doubt gravely disappointed.

Hayes departed in the tenth episode of the season, titled Living in a House Divided, after resigning in the previous episode due to a twist in a storyline involving Dr Owen Hunt.

The character's final episode aired in the UK on Wednesday 4th May 2022.

Flood's exit comes after last season saw exits for three series regulars in the form of Giacomo Gianniotti (Dr Andrew DeLuca), Jesse Williams (Dr Jackson Avery) and Greg Germann (Dr Tom Koracick) - although Germann and Williams have since returned as a guest stars.

Jesse Williams and Sarah Drew return for the finale

Jesse Williams and Sarah Drew are set to reprise their roles as Dr Jackson Avery and Dr April Kepner in the season 18 finale.

The pair was last seen in season 17 when Jackson departed Seattle and visited ex-wife April in an episode that saw her reveal she had split from her second husband, Matthew.

April agreed to move away with Jackson as he worked on his foundation and bring their daughter with them.

Have the pair reconciled romantically? Japril fans will certainly hope so.

Is there a trailer for Grey's Anatomy season 18?

ABC shared a promo for the season 18 premiere back in September, teasing Teddy and Owen's wedding as well as Meredith's doubts over her plans for the future.

Meanwhile, those excited for the return of Kate Walsh as Addison Montgomery are in luck as ABC released a sneak-peek of her grand entrance in episode three.

In a callback to her iconic introduction in the very first season, the clip shows Addison greeting the hospital staff with: "And you must be the group that's been screwing up the programme."

What happened in Grey's Anatomy season 17?

It was an emotional season for longtime viewers of Grey's Anatomy as lead character Meredith Grey has been in a coma for much of it, suffering from a severe case of COVID-19.

The writers have prevented the show from becoming too bleak by gifting Meredith with some touching dream sequences as she lay unconscious, which have taken the form of picturesque beach reunions with long-absent friends.

The confirmed return of Ellen Pompeo always indicated that Meredith would wake up and recover from her illness, after some fans had worried she could succumb to her serious condition.

Meanwhile, in the real world, life at Grey Sloan Memorial Hospital remains very busy indeed, with the one of the biggest developments being Jackson Avery's decision to leave the medical facility.

Following recent traumatic events, he now strives to create "real racial equity" in medicine and will move to Boston in order to work towards that goal.

In Jackson's final episode, which aired in May 2021, Grey's also bid farewell to another of its biggest personalities, that being Dr Tom Koracick (played by Greg Germann), who decided to team up with Jackson on his new endeavour.

However, Koracick isn't leaving the medical drama permanently, as showrunner Krista Vernoff has confirmed the character will return as a guest star in the future.
