There is a big event coming in Station 19 season 4 finale, which comes with the title "Forever and Ever, Amen." Maya Bishop (Danielle Savre) and Carina DeLuca (Stefania Spampinato) take the center stage, as the couple finally takes their relationship to the next level.

In Station 19 season 4 finale, Maya and Carina decided to get married and make everything official between them. This is an important event for both of them, especially with what they've been through as of late -- and even on the verge of breaking up.

Maya and Carina almost separated, but they managed to save their relationship and were engaged shortly after. Their wedding is a significant event not only for them but also for the people around them. It's going to be a celebration of their love, as well as making it through the tough times.

The promo of Station 19 season 4 finale further hypes their nuptials. Everyone looks happy as Ben Warren (Jason George) walks the two down the aisle. The clip teased a lot of heartfelt and emotional scenes are coming during the event.

However, the celebration might be hitting a bumpy road as there could be unforeseen things that could make the situation a bit complicated. For instance, Maya's family needs to process and contend with a major part of her life. As the synopsis notes, she "addresses some unresolved family issues."

In addition, most of the firefighters need to deal with the fire, which could put some of them in grave danger. In fact, the crew will take matters into their own hands after being caught up with a life-or-death moment on scene. The clip also teases intense moments for everyone while working.

Elsewhere in Station 19 season 4 finale, Andy Herrera (Jaina Lee Ortiz) and Robert Sullivan's (Borris Kadjoe) marriage will be tested. These two have also been facing issues in their relationship, and it's yet to be seen whether they could settle all things up.

Meanwhile, there is no need to worry about the future of the series since it's already renewed for season 5. Thus, the episode may leave a cliffhanger that will be resolved in the next installment. It could either be a personal storyline or something related to their job.

The personal storyline might be all about Maya's dealing with her past struggles and trying to find peace. As for something job-related, the crew's mission could put their lives on the line, leaving their fate in question moving forward.

Station 19 season 4 finale airs on Thursday, June 3, on ABC.
