The Waverider might be losing a crew member in Season 3 of CW’s “Legends of Tomorrow.”

In a recent interview with ComicBook.com, executive producer Phil Klemmer teased that there might be a major character death coming later in the season.

“All the Legends are not going to be fine,” Klemmer said of what fans can expect from the rest of Season 3. “I think that’s something that we said very early on; when we were talking about a show that we hadn’t even made at Comic Con three years ago, we said this show was an ensemble, and it was one where we would have a rotating cast, and that when people died, they would die in real life.”

“It’s been a long time since Hawkman (Falk Hentschel) got stabbed or whatever. It’s been a long time since Hawkgirl (Ciara Renée) flew away,” Klemmer continued. “Our show really got to be super-funny last year, but I feel like you have to leaven that comedy with some hardcore pathos and some real-world stakes.”

While it’s unclear who among the Legends will die this season, the most obvious candidate for a character death so far is Professor Martin Stein (Victor Garber).

Deadline confirmed  earlier this month that Garber will be exiting the series this season. Rumblings about the actor’s departure first surfaced when the show was wrapping its sophomore run. The rumors intensified over the summer, and while the CW and the show’s producing studio Warner Bros. TV have yet to comment on the news, Garber’s imminent exit was inadvertently made clear in September when it was revealed that he would return to Broadway to star in the Tony-winning revival of “Hello, Dolly!” Garber is set to replace David Hyde Pierce as Horace Vandergelder in the stage play, and his first show is scheduled on Jan. 20 next year.

Garber’s departure seems to have been planned ahead of time. In the Season 3 premiere, it was revealed that Garber’s Stein is going to be a grandfather. Although the physics professor decided to stay on the Waverider at the final moments of the episode, he only did so under the proviso that he would return to Central City 2017 in time for the childbirth of his daughter Lily (Christina Brucato). But will he get back home alive?

“Legends of Tomorrow” Season 3 airs Tuesdays at 9 p.m. EDT on The CW.
