In the first draft script of ENT: "Fusion" (which had the working title "Equilibrium"), Trip Tucker explained to Fraht that costumes were typically worn at Halloween (including to go trick-or-treating). Tucker also recalled that, in his childhood, he had usually dressed up as either an alien or an astronaut for Halloween. He told Fraht that wearing a costume was a condition of an upcoming Halloween party which was to be held aboard Enterprise NX-01. However, Fraht was initially unsure what costume he should wear to the party. After Fraht reasoned that he was an alien among Humans, Trip advised him to come to the party just as he was.
