It was good to finally see Andoria, but the story was a little disappointing, considering all the build-up in the last two episodes.
Synopsis from StarTrek.com
After learning that the brainwaves used to control the menacing drone ships belonged to a member of an Andorian sub-species of telepaths called the Aenar, Archer and Shran set off for Andoria to discover the culprit's identity. After a long and perilous journey through the freezing Androrian climate, Archer and Shran meet Jhamel, an Aenar woman who valiantly offers to help in their quest. Jhamel agrees to join them on Enterprise to test a telepresence unit, which can be extremely dangerous, in order to make contact with the Aenar who is telepathically controlling the drone ships. Jhamel fears that her brother, Gareb, whom she thought was dead, is the Aenar responsible for the drone ship attacks.
Meanwhile, to cover their tracks for their previous failed missions, Nijil and Valdore set their plan into motion to have their Aenar use the two Drone ships to finally destroy Enterprise.
Aboard Enterprise, Jhamel uses the telepresence unit to contact Gareb, who has already engaged the two Drone ships to fire upon Enterprise. Jhamel's love for her brother is able to permeate his brainwashed state, and Gareb stops the attacks. After Valdore shoots Gareb for disobeying his orders, Jhamel takes great comfort in the fact that her brother died a hero.
Realizing his personal feelings for T'Pol are affecting his work, Trip asks Archer to transfer him to another ship.
----------------------------
Trip actually asks to be transferred to the Columbia. Apparently they have asked for him twice already.
I wondered why the Aenar, when they could repair Shran's leg, couldn't repair his antenna. I would have thought an antenna, which Phlox said would grow back quicker with stimulation, would be easier to make better than a gaping hole in the thigh.
They have still not explained where the dark-skinned, blond haired, longer striped antennaed Andorians come from that were seen in TNG in 'The Offspring' and in 'Captain's Holiday'.
