Station 19 season 4 episode 5 will be the final one for the firefighter drama this calendar year. Just like its flagship show, Grey's Anatomy, the series is going on a winter break. Here is what viewers can anticipate in the upcoming "Out of Control."

Station 19 season 4 episode 5 is going to feature a crossover event with the medical drama. A lot of significant stories are coming here, with most of the characters from both shows in danger. In the spin-off, Dean Miller (Okieriere Onaodowan) is the biggest concern.

The firefighters go into action while off duty. However, their heroic act to help a mother in distress leads to a conflict with the police officers. The promo of the upcoming episode sees the crew taking on a potential kidnapping crisis. But then, there will be a huge conflict at the center of it.

The firefighters are doing their best to save lives and maintain peace at times like this. However, they aren't police officers, which could spark a problem between the two departments. Tensions arise leading to more troubles in Station 19 season 4 episode 5.

Despite that, Miller puts his life on the line just to save those who are in danger -- even if that means risking his own life in the process. Yet, his action isn't surprising to many since this is actually how and who he is. He won't just stand there and watch other people in a dangerous situation.

It remains to be seen whether or not Miller is going to be fine before Station 19 season 4 episode 5. Still, many were optimistic that the series won't lose a character like him. After all, he and Robert Sullivan (Boris Kodjoe) are moving forward and patching things up.

Also, it's clear that there's something more between him and Vic Hughes (Barrett Doss). The two aren't romantically involved, but they could be heading in that direction later on in the series. They could find a way to make things work amidst all the challenges coming for them.

Meanwhile, the upcoming episode also brings stories to other characters. For instance, Andy Herrera (Jaina Lee Ortiz) and Sullivan try to figure out how to stay connected, while Jack Gibson (Grey Damon) and Inara (Colleen Foy) starts to get even closer. Ben Warren (Jason George), on the other hand, must confront a tough loss.

Station 19 season 4 episode 5 arrives on Thursday, Dec. 17, on ABC.
