Before she was Tasha Yar, she was Lieutenant Commander Macha Hernandez.

For the Season 14 finale of The Trek Files, Denise Crosby joins Larry Nemecek to revisit her original 1987 audition sides for Star Trek: The Next Generation, including early character descriptions that reveal a very different version of the Enterprise's security chief.

Denise first read for Deanna Troi before Gene Roddenberry made a pivotal switch, reshaping the role of Macha Hernandez into Tasha Yar to fit Denise's strengths. In this week's episode, Denise reflects on the audition process, her favorite scene between Troi and Yar that was never filmed, and what those early creative decisions revealed about the direction of TNG.

She also shares memories of those uncertain early days of production, the risk of launching a syndicated sequel to an iconic series, and the emotional complexity of stepping into (and eventually stepping away from) such a historic role. Along the way, Denise speaks movingly about loss after the Palisades fire, resilience, fandom, and what it means to revisit Star Trek decades later.

It's a revealing look at how a character evolves, how casting can reshape canon, and how even discarded script pages tell the story of Star Trek's creative DNA.

In this very special episode of The Trek Files, actor Robin Curtis joins us to revisit a little-known chapter in Saavik's story, one that never made it to screen. Drawing from a pair of early Star Trek IV: The Voyage Home script drafts, we explore a scene that implies Saavik is pregnant with Spock's child, a narrative thread begun in Star Trek III but quietly dropped by the time the final film was released.

Robin shares warm memories of working with Leonard Nimoy, the late Harve Bennett, and her fellow castmates, as well as a few eye-opening truths about the unpredictability of Hollywood. Plus, she discusses her return to the role of Saavik in OTOY's Unification, and we recreate the pivotal, never-filmed scene between Kirk and Saavik.

It's an emotional, candid, and deeply human conversation about legacy, missed opportunities, and what it means to carry a character with you for decades.

Before Star Trek: Discovery's final season sent its crew in pursuit of ancient secrets, Carlos Cisco had already taken inspiration from one of the most profound episodes of The Next Generation, "The Chase." In this week's The Trek Files, Carlos returns to explore the thematic connections between the 1993 TNG episode and Discovery's modern narrative arc. With Larry Nemecek, he discusses how "The Chase" influenced the creation of the alien species Progenitors and how its ideas about shared ancestry and unity resonated with the story of L'ak and the Breen in Discovery Season 5.

Document and additional references: Star Trek: The Next Generation episode "The Chase," final draft script (revised Feb 4–10, 1993)

Written by Ronald D. Moore & Joe Menosky, directed by Jonathan Frakes.
