WARNING: This article may have spoilers for Station 19 season 3 finale. Read at your own risk.

Station 19 season 3 finale is coming on Tuesday on ABC, with the title "Louder than a Bomb." This is an interesting episode as it features the biggest Grey's Anatomy crossover so far. In addition, the episode marks the first appearance of Ellen Pompeo as Meredith Grey in the spin-off.

Station 19 season 3 finale will bring different emotional stories, especially for Andy Herrera. She has been dealing through a lot as of late, losing her father Pruitt and friend Ryan. Entering this episode, she's going to deal with the surgery of her husband, Sullivan.

It also seems like Andy and Meredith will have some sort of interaction within this episode. Based on some preview photos, the two are seemingly having a serious conversation. Perhaps, Meredith brings medical wisdom since Andy is struggling to deal with what's going on with Sullivan.

Meredith could likely offer reassurance and tells Andy that everything will be okay. But then, there's also a chance that the two would have a much deeper conversation. Andy will probably open up to Meredith about what she's currently going through.

Meredith could understand what Andy has been dealing with, considering that she's also gone through a lot -- losing Ellis, Thatcher, and Lexie. She has been in emotional pain and endured a lot of tragedies, so she could likely understand Andy's feelings.

Andy could see Meredith as a shoulder to lean on. While they may not spend a lot of time together, it's still interesting and exciting to see their interaction. Perhaps, their deep conversation could also lead to a blossoming friendship. After all, they both understand each other.

As for what else is coming for Andy in Station 19 season 3, she'll be dealing with some family secrets. She is suspicious about her mother's death and will try to uncover what really happened. She goes to her aunt to seek answers and may discover some painful things along the way.

Andy could also learn some shocking secrets that will lead her to further exploring her family history. She needs to do it by herself now that her father is gone. The episode may also leave some cliffhangers that could potentially be explored in the future.

Also, there's another concern within this episode. Some were worried it will feature again another unexpected death. The series isn't afraid of doing such thing, as it already featured several characters' deaths this season.

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