In a scene deleted from "Fight or Flight", Ensign Travis Mayweather also referenced Draylax in a similar game he played with Archer. Mayweather and Archer actually used the same locations as Tucker and Archer later.
According to Archer, in the year 2151, the farthest that humans had traveled from Earth was 90 light years. Draylax was visited by humans prior to this year. (ENT: "Two Days and Two Nights")
