Captain Benjamin Sisko's (Avery Brooks) parting words in Star Trek: Deep Space Nine became his saddest quote of all, because it was a promise that Star Trek itself couldn't keep. Star Trek: Deep Space Nine ended in 1999 with its series finale, "What You Leave Behind," which resolved Sisko's destiny as the Emissary of the Prophets and Bajor's savior.

Captain Sisko's powerful quotes are on par with the most famous lines from his peers like Captain James T. Kirk (William Shatner) and Captain Jean-Luc Picard (Patrick Stewart), yet they are still underrated in comparison. Avery Brooks' performances as Sisko have riveted audiences, such as his mental breakdown as Benny Russell, crying out, "It's real!" in Star Trek: Deep Space Nine's "Far Beyond the Stars."

Perhaps Captain Sisko's most notorious line was when he broke the fourth wall and spoke directly to the viewers at home, repeating, "I can live with it," after secretly committing war crimes in Star Trek: Deep Space Nine's "In the Pale Moonlight." However, the last words by Captain Sisko in Star Trek: Deep Space Nine's finale are hauntingly sad because they never came true; at least, not for Star Trek fans.

Captain Sisko’s Last DS9 Quote Was A Promise Star Trek Couldn’t Deliver

At the end of Star Trek: Deep Space Nine, Captain Sisko and Gul Dukat (Marc Alaimo) plunged into the Fire Caves of Bajor. Sisko entered the Celestial Temple as the Emissary, shedding his corporeal form and becoming a non-linear being like the Prophets that created him. Benjamin then reappeared to his wife, Kasidy Yates (Penny Johnson Jerald), to say goodbye. When she asked when he'd be back, Sisko made a promise:

“It’s hard to say. Maybe a year. Maybe yesterday. But I will be back.”

Sadly, Star Trek couldn't fulfill Sisko's promise because Star Trek: Deep Space Nine was over, and there would be no canonical continuation. While there were discussions of a Deep Space Nine movie following Star Trek: The Next Generation to the big screen, that never came to fruition or was seriously considered since DS9 didn't achieve the widespread popularity of TNG.

Further, executive producer Ira Steven Behr told Star Trek: Deep Space Nine's story to its conclusion. When "What You Left Behind" was over, many DS9 characters left the space station to pursue new lives. While there was the 2019 DS9 documentary, "What We Left Behind," it would be a couple of decades before Star Trek on Paramount+'s shows began providing canonical updates to DS9, with a few characters appearing on Star Trek: Lower Decks.

Finally, Avery Brooks himself retired from acting in the 2010s and distanced himself from Star Trek. While Patrick Stewart and Kate Mulgrew reprised their iconic captains in Star Trek on Paramount+'s shows, a Deep Space Nine reunion was stymied without Brooks and Captain Sisko, its main character, along with the tragic deaths of cast members Rene Auberjonois and Aron Eisenberg.

Star Trek Finally Addressed Captain Sisko 27 Years Later

27 years after Star Trek: Deep Space Nine ended, Star Trek: Starfleet Academy gave Captain Sisko and DS9 their due. Starfleet Academy turned what happened to Captain Sisko in the Fire Caves of Bajor into an unsolved mystery that has endured for 800 years. Sisko himself faded into legend, with his exploits as a Starfleet captain and the Emissary of the Prophets enshrined in his own museum.

In Star Trek: Starfleet Academy episode 5, "Series Acclimation Mil," Cirroc Lofton became the first and only Star Trek: Deep Space Nine actor to reprise his character in live-action. Lofton returned as a manifestation of Jake Sisko to give SAM (Kerrice Brooks) personal insight into his father. While not stated outright, it was implied that Captain Sisko did occasionally reappear to his loved ones.

Star Trek: Starfleet Academy episode 5 ended with a special voiceover by Avery Brooks that Lofton got permission to use in the episode. It was as if Captain Sisko was speaking to audiences from the Celestial Temple for the first time. Look closely at the clouds over San Francisco, and the Emissary's image can be seen, still watching over us all.

When Sisko became a Prophet, linear time lost all meaning to him. Benjamin lives in another plane of existence, so he is no longer concerned with or aware of the passage of time for mortals by the very nature of being a Prophet. While Star Trek fans never saw it, it's very likely that Benjamin did keep his promise to Kasidy and the child she was pregnant with at the end of Star Trek: Deep Space Nine.
