Aired five months after longtime cast member David McCallum's death, making it the first NCIS episode and the first NCIS season premiere to air after his death.
David McCallum is still credited in this episode despite having passed away five months earlier. This is the first season to not feature McCallum as Ducky.
David McCallum, who played Ducky since the first episode of NCIS, died on September 25th, 2023. He was the last remaining member of the original cast. He died before any episodes of the 2023 were able to be broadcast due to the writers strike, which coincidentally was settled on the day of his death.
Algún Día means "Some Day" in English.
