The "Star Trek: Voyager" unique character Kes (played by Jennifer Lien) offered many interesting opportunities for the series, but unfortunately, it didn't come to fruition.

Kes, known for her telepathy and nine-year lifespan, was written out of the series after three seasons, a departure the cast and crew lamented.

At the time, the reasons for Lien leaving the show were a little murky. Writers confessed to feeling they wrote themselves into a corner with her character.

However, later producers disclosed that her increasingly unstable mental health forced them to let her go. Producer Jeri Taylor expounded on this in a 2020 book about the series.

Taylor explained, "She wouldn't talk or let us offer to help." With no other foreseeable options, showrunners decided to write her out of the show.

Unfortunately, problems persisted for Lein after “Voyager.” She was arrested for indecent exposure in 2015 and again in 2018 for driving on a revoked license.
