spokesperson, Lissan (Alicia Adams), initially declines to assist as the Aenar do not want to get involved in a war. However, a young Aenar named Jhamel (Alexandra Lydon) decides to help, since doing so may help locate Gareb (Scott Allen Rinker), her missing brother. Meanwhile, Doctor Phlox (John Billingsley), Commander T'Pol (Jolene Blalock), and Commander Charles "Trip" Tucker III (Connor Trinneer) work in Sickbay on their own "telepresence" unit to help counter the drone ship. T'Pol volunteers to test it, and a concerned Tucker finds it increasingly difficult to balance his duties and emotions. Jhamel then tests the unit, with better results. Later, when the drone ships reappear and attack, she is able to contact the drone pilot, and it is indeed her long-lost brother, who was tricked into working with the Romulans. Learning the deception of his "helpers", he turns the drones on each other and both are soon destroyed, and Valdore angrily kills him in retribution. With the threat resolved, the Andorians depart Enterprise and Tucker requests to leave the ship to join the Columbia. Production "The Aenar" was the third and final part in the Romulan story arc, comprising "Babel One", "United" and "The Aenar". It was written by André Bormanis from a story by show runner Manny Coto. Bormanis had also written "Babel One", and earlier in the season the episode "Awakening", which formed part of the Vulcan story arc. "The Aenar" was directed by Mike Vejar, his third episode of the season. This episode was the first time the homeworld of the Andorian race was represented on screen. The race had been introduced in the Star Trek: The Original Series second-season episode "Journey to Babel". The interior of a sound stage was fitted out to appear like caverns on the ice world as it was theorized that this was the environment in which a race such as the Andorians, including the Aenar sub-species, could have evolved. These sets were enhanced in post-production using computer-generated imagery. Filming began on November 22, 2004, and was completed on December 2, with the production being halted for two days due to Thanksgiving. The majority of the guest stars from earlier installments of the trilogy returned for "The Aenar", and they were joined by Alexandra Lydon and Alicia Adams, who were both making their first appearances in a Star Trek series. Kim Koski was the stunt double for Jeffrey Combs
