This is the only Star Trek appearance of Dean Stockwell, co-star with Scott Bakula for five years on Quantum Leap (1989).
Grat is shown operating a PADD similar to a handheld computer known as a handlink, which Dean Stockwell's character Al used in Quantum Leap (1989) to communicate with the show's artificial intelligence, Ziggy.
Grat refers to the events of Cold Front (2001), and states that the incident occurred "approximately three months ago." Although no exact date is given for the events of this episode, this would seem to indicate an approximate date of December 2151.
Both Dennis Christopher and Christopher Shea played Vorta in Star Trek: Deep Space Nine (1993). Christopher appeared as Borath in The Search, Part II (1994) and Shea appeared as Keevan in Rocks and Shoals (1997) and The Magnificent Ferengi (1998).
Christopher Shea (Sajen) also played Taowin in Think Tank (1999) and later played Telev in Cease Fire (2003).
