‘9-1-1’ Season 9 Trailer: Hen & Athena Head to Space While the 118 Deals With the ‘End of the World’ (VIDEO)

It’s “the end of the world,” as Chimney (Kenneth Choi) puts it in the new 9-1-1 Season 9 trailer released on Thursday, October 2, one week before the premiere. And no, it’s not just because the 118 must continue to move forward without its captain, Bobby Nash (Peter Krause), after his tragic death in Season 8 Episode 15.

Rather, the 118 — specifically Eddie (Ryan Guzman), diving into the water, then Hen (Aisha Hinds), performs CPR — saves a billionaire, Trip (Mark Consuelos), who’s swallowed by a whale. Trip invites Hen to space on a historic flight. Hen, of course, asks her wife, Karen (Tracie Thoms), but she’s completely against it. “I am a serious scientist,” she protests. “Trip Hauser doesn’t care about serious science. I can’t go to space.”

Hen then invites Athena (Angela Bassett), who turns her down — “Are you crazy? Absolutely not.” — at first. The 118 then watches the launch — among those also going up is a character named Tricia Benoit (played by June Diane Raphael) — but what no one knows is that Trip was warned before about a geomagnetic storm by Cody Whitting (guest star Max Carver) and refused to stop it. All contact is then lost with the spacecraft, with Athena and Hen in the middle of the chaos in space. The 118, meanwhile, deals with the chaos that ensues in Los Angeles as a result.

Watch the trailer above for much more of what’s going on in space, including Hen grabbing onto Athena as she’s starting to float outside the vessel.

The series will be back for Season 9. Below, we’ve gathered everything we know about 9-1-1 Season 9, from that date to its cast and much more.

When will 9-1-1 Season 9 premiere?

9-1-1 Season 9 will premiere on Thursday, October 9, at 8/7c, on ABC. (That’s a week earlier than originally announced.) It will consist of 18 episodes.

It will be followed by the new 9-1-1: Nashville spinoff — get all the details about that show here — and Grey’s Anatomy.

Who will be in the 9-1-1 Season 9 cast?

Sadly, we now know that Peter Krause will not be back, following Bobby’s death. (He did, however, appear again in Season 8, as showrunner Tim Minear told TV Insider he would.) The end of Season 8 established that no one else is leaving the 118, so Angela Bassett (as Athena), Oliver Stark (as Buck), Aisha Hinds (as Hen), Kenneth Choi (as Chimney), Jennifer Love Hewitt (as Maddie), and Ryan Guzman (as Eddie) will all be back. Upped to series regulars for the new season are the actors who play Athena’s kids, Corinne Massiah (May) and Elijah M. Cooper (Harry).

How did the 9-1-1 Season 8 finale end?

The 118 and Athena worked together to save victims of a building collapse. Eddie was on his way to the airport when he saw the news and showed up to help rescue Buck and Ravi (Anirudh Pisharody). After, Chimney declared that no one else was leaving the 118, meaning Eddie wasn’t moving back to Texas and Buck wasn’t transferring out.

“This is our firehouse. This is the 118. And it’s not just a number, it’s us. And you’re right, Buck. Things are never going to be the same again because Cap is gone. But leaving won’t change that. It won’t make you feel any less sad. It just means that you’ll be sad all alone. Bobby died so I could live, and it has screwed me up in ways I can’t fully express, but the truth is, he would have done that for any one of us. He knew that just coming into work every day, there’s a chance that one or more of us would not make it home, and his job above everything else was to make sure that we did. And we are all standing here right now because of him. This team, we are his legacy. So we can miss him, and we can mourn him, and we can even curse his name, but we are not going to disrespect him by throwing away what he built right here. So you hang up your turnouts, you hit the showers, you go home, and you get some rest because we are all going to see each other on our next shift, right here, together. Understood?” Chimney checked, and Hen immediately responded with, “Copy that, Cap, I mean, Chim.”

The finale ended with Maddie having given birth to her and Chimney’s son Robert Nash Han, Athena selling the house she and Bobby were building together, Eddie moving back into his home, Buck looking for a new place, and Hen and Karen (Tracie Thoms) officially adopting Mara.

Why '9-1-1's First Major Death Was Perfectly Devastating

Who will be the 118’s new captain in 9-1-1 Season 9?

Chimney’s stepping in as interim captain, which his speech near the end of the Season 8 finale set up. Both Aisha Hinds and Oliver Stark told TV Insider they’d be all for that when they stopped by our office to discuss the Season 8 finale.

“I think that Hen has tremendous respect for Chimney, and so I think that she would give him the support and the respect that that role requires. I think for Hen in particular, though the chief offered the position to her, she’s always been able to jump in and out of the role knowing that Bobby was coming back to it. And so I think this puts it in a different context for her,” Hinds said. “And so I think she felt comfortable kind of declining that position.”

Stark agreed. “It’s a job that Buck probably sees himself one day hoping to do, but I don’t think he would feel comfortable wanting that position now. I think he looks at Hen and Chimney and he’s like, ‘Those are the people that I look up to.’ They’re every bit cut from the same cloth as Bobby was, and I think he’d have nothing but admiration and respect for Chimney in the role.”

Is there a 9-1-1 Season 9 trailer?

Yes, and you can watch it above for a look at Athena and Hen going to space and the emergency situation both up in their spacecraft and back in Los Angeles.
