Station 19 season 3 episode 12 is coming next week on ABC, with the title "I'll Be Seeing You." The series keeps on delivering exciting moments every week. But, the upcoming episode will probably be a dramatic and heartbreaking one as one of the firefighters may possibly meet his/her ultimate demise.

The promo of Station 19 season 3 episode 12 hinted that "one firefighter will fall," with some speculating that there will be another death before the episode ends. Some fans were worried another character may depart from the show, and this would be the third death this season -- if ever.

The clip is a bit concerning, as it likely suggests that the series could be losing again one of its core characters as some point in the episode. The promo showed the firefighters are in a difficult situation and some of them are in danger.

Everyone was shaken when Ryan Tanner (Alberto Frezza) died earlier this season. And then, Rigo Vasquez's (Rigo Sanchez) death also took a toll on everyone's mental health. Hence, it would be another devastating moment if something bad happens to Sullivan, Dean, Jack, Vic, Maya, Andy, or Travis.

Meanwhile, there will be another Grey's Anatomy crossover in Station 19 season 3 episode 12. Jesse Williams' Dr. Jackson Avery will be appearing again the episode but in a different circumstance this time. He will be helping Ben on something new; putting on a jacket and running into burning buildings.

Based on the synopsis, the Station 19 crew will deal with the dangerous situation as they battle a storage facility with growing complications. Then, Dr. Avery suddenly pops over from Grey Sloan and he ended up collaborating with his old pal Ben.

But aside from Williams' Dr. Avery, there is also another familiar face appearing in this episode: Carina and Nico. The appearance of the latter might be surprising given that he and Levi broke up just recently. But, it remains to be how much more of this character we're going to be seeing.

Meanwhile, this episode wasn't promoted as a season finale, so there's still a chance the series will be delivering a few more episodes in the coming weeks. The future of the season is still uncertain right now, considering the health crisis happening around the world right now.

Station 19 season 3 episode 12 airs on Thursday night, Apr. 12, on ABC. New episodes of the series can also be watched the next day on demand and on Hulu.
