|Out of universe information|
After the Tagrean Stargate had been located by a search team led by Teal'c and Jonas Quinn, both of whom were subsequently captured by forces under the command of Kalfas, DeLouise piloted the Prometheus to the site as part of O'Neill's plan to resolve the situation. (SG1: "Memento")
DeLouise's name is never spoken on screen, and he is credited only as "Navigator," but the name ("Peter DeLuise" without "o") was printed on his uniform. This may have been an homage to Peter DeLuise, who directed "Memento" as well as many other episodes. Ray Galletti clarified that it was Peter DeLuise's idea to name the character after himself. DeLouise surname (with "o") is mentioned only on IMDb.
