	Crown Prince Abdullah of Jordan makes a cameo appearance as the crewmember Kim is talking to in the corridor when Neelix comes up and asks him what Kim thought of his programme 'A Briefing With Neelix'. The Crown Prince is seen again later, talking in a corridor.
	The interiors of the Talaxian ship that Laxeth calls Neelix and then Voyager's bridge from are the same as those used to portray Neelix's ship (which is later named as Baxial, "Alice").
	"Investigations" was filmed before "Lifesigns" but aired afterwards to maintain plot continuity as regards the plan to have Paris unmask the traitor aboard Voyager.
	Raphael Sbarge has his final appearance as Jonas in this episode. He previously appeared in "Alliances", "Threshold" and "Lifesigns".
