In this episode, many of the Xindi get names: Rick Worthy's Xindi-Arboreal is Jannar; Scott MacDonald's Xindi-Reptilian Commander is Dolum; and the main Aquatic is Kiaphet Amman'sor, of the Ibix Dynasty.

T'Pol tells Reed at one point, "The needs of the many outweigh the needs of the few." Spock said that to Kirk in Star Trek II: The Wrath of Khan.
