Rebecca Romijn Teases Game-Changing Season 4 Storyline for Number One on Star Trek: Strange New Worlds

If you’ve been itching to know what Star Trek: Strange New Worlds has cooked up for Season 4, especially when it comes to Rebecca Romijn’s Una Chin-Riley (aka Number One), there’s finally some concrete news—complete with a few juicy details from Romijn herself. And honestly, if you’re a fan of seeing familiar faces pushed in new directions, you’ll probably be into this.

No More Sidelines for Una

Romijn recently opened up about what’s ahead for Una in the next season, and it’s a noticeable shift from what we’ve seen so far. The big change? She’s stepping up and leading more of those away-team missions. In other words, Number One is done playing backup—season 4 is putting her right up front, giving her a lot more agency (and screen time, if we’re being real).

"We get to see a much freer Una, who gets to lead missions starting in Season 4 and 5… It’s so exciting, it’s so fun."

Romijn shared this at CCXP Mexico (which seems to be the latest stop for dropping Star Trek tidbits), spelling out that Una actually asks for more responsibility on the ground right at the top of season 4. She’s living more authentically now—a callback to the character’s previous storylines—and apparently, that means boldly going on some pretty substantial missions herself.

Teaser Confirms: Una’s All Over the Action

During the CCXP Mexico presentation, Romijn was joined by series regulars Ethan Peck, Celia Rose Gooding, and Paul Wesley—so the promo push is officially underway. The teaser trailer played at the event gave fans a sneak peek at Una on-planet, working side by side with Captain Pike (still played by Anson Mount, in case you were worried).

Some new stills have also landed, and they back up Romijn’s claims: expect Una leading missions with La'an Noonien-Singh (Christina Chong) and Erica Ortegas (Melissa Navia). Basically, if there’s some action dirt-side, chances are Una’s right in the thick of it instead of just giving orders from the ship.

Mark Your Calendar

• Star Trek: Strange New Worlds Season 4 launches July 23 on Paramount+.
• Cast members featured in the rollout: Rebecca Romijn (Una/Number One), Ethan Peck (Spock), Anson Mount (Pike), Celia Rose Gooding (Uhura), Paul Wesley (Kirk), Christina Chong (La'an), Melissa Navia (Ortegas).
• Expect early storylines to focus on Una requesting and getting more 'on-planet' responsibility.
• Yes, this is all confirmed by new footage and promotional images—not just the usual vague promises.

So if Season 4 felt like it couldn’t come soon enough, at least now you know: more missions, more on-the-ground action, and a lot more Rebecca Romijn steering the ship (sometimes literally, sometimes not). Looks like Number One is finally getting the spotlight she deserves—and it’s probably going to be a blast watching what she does with it.
