Kes (Jennifer Lien) reacts poorly to Tuvix as his existence deprives her of both Tuvok and Neelix, her mentor and boyfriend respectively. Her displeasure lessens over the course of the episode, but never completely goes away. Captain Janeway (Kate Mulgrew) accepts Tuvix in his role as an excellent chief tactical officer and "an able advisor, who skillfully uses humor to make his points". Tuvix himself, having the combined memories and personalities of his constituents, melds the previously intractable qualities of both and improves upon them, flexing either muscle as the situation requires: "Chief of security or head chef, take your pick!"
