There are a lot of intense scenes happening on 9-1-1 season 3 episode 4, especially now that we're moving past the tsunami event. The upcoming episode, titled "Triggers," will now focus more on what's happening in the present time, as well as the aftermath of the disaster. Based on the title alone, it seems like this episode will also feature action-filled and emotional scenes.

In 9-1-1 season 3 episode 4, we're going to see some emotional aftermath following the chaos, particularly for Christopher. Being with this kind of situation and trying to handle a crisis like that wouldn't be easy, especially for a young child. The good thing is that Eddie was there, and he will help Christopher cope with the trauma of the tsunami.

Apart from the aftermath of the disaster, 9-1-1 season 3 episode 4 also sees the first responders doing everything they can to stop a wide array of problems. They need to save the workers in a high-rise during a fire drill -- a mother and a son who got involved in a car accident, as well as siblings fighting over a family heirloom.

Will the first responders clear up all these problems before it's too late? That's one of the big questions in the upcoming episode and we're going to get answers next week. But, one thing is for sure though: this episode will deliver dramatic moments from these scenarios.

In addition, the upcoming episode will also feature Buck delivering surprising news to Bobby, Hen and Karen debating on whether expanding their family or not, and Maddie decides to take action against a possible wife abuser. These are just some of the interesting things in "Triggers" and, for sure, there are also other unexpected events beyond the synopsis.

Moreover, next week's episode also seems to have a concentrated effort, which is focusing more than just what's going to happen to the rescuers and their missions. It's something that creates and establishes a sense of care for these characters, like what happened to Christopher, and this makes the series more interesting.

Meanwhile, some of the guest stars in 9-1-1 season 3 episode 4 includes Ronda Rousey (as Lena Bosko), Tracie Thomas (Karen Wilson), Declan Platt (Denny Wilson), Bryan Safi (Josh Russo), Scott Wilder (Alan), Jordan Belfi (Chase Mackey), Jonathan Ohye (Dr. Lin), Paula Jai Parker (Judith Spivey), Aiden Berryman (Camden), and Jonny Berryman (Jonny).

9-1-1 season 3 episode 4 will arrive on Monday, October 14, on FOX.
