Station 19 season 3 finale is set to arrive within a few weeks on ABC. This episode proved to be interesting as we're going to see some characters from Grey's Anatomy. This is the biggest crossover event so far, which will feature the lead star of the medical drama series: Ellen Pompeo.

Pompeo's presence in Station 19 season 3 finale marks the first appearance of her character Meredith Grey on the spinoff series since the premiere. This will be an interesting episode and it's exciting to see how she will interact with some of the firefighters.

But aside from Pompeo, other Grey's Anatomy cast set to appear within this episode includes Stefania Spampinato, Kim Raver, and Caterina Scorsone. There's a possibility that these characters' arrival may have something to do with the aftermath of the drama at Pac-North hospital.

Based on the synopsis, the crew members evacuate a doctor from Pac-North hospital but find themselves in a life-threatening condition. It can be recalled that the Pac-North served as the hospital for some alum of the Grey Sloan and worked there early on season 16.

Sullivan will also undergo surgery for his chronic leg pain, so one of the doctors from Grey Sloan will likely attend to him. It remains to be seen what would be the future of this character, given that the series tends to deliver unexpected surprises.

Perhaps, this episode will probably leave some huge cliffhangers. There have been a lot of concerns regarding the future of some of the cast members. The series has early killed off several characters earlier this season, so there could be a potential concern here.

Meanwhile, Andy Herrera will also have a big storyline in Station 19 season 3 finale. She'll learn some shocking things about the death of her mother and this could lead to her exploring more of her family history in the fourth installment.

According to the synopsis, Andy is becoming painfully suspicious of the circumstances regarding her mother's death. To understand more what really happened, she goes to her aunt to seek some answers. Perhaps, she'll uncover some painful secrets along the way.

Andy's journey this season has been a tough one, given that she lost her father, Pruitt. And since Pompeo's Meredith will appear in this episode, the two women will likely have some sort of pep talk. They have been always connected, especially when facing a crisis.

Station 19 season 3 finale airs on Thursday night, May 14, on ABC.
