Problems
- The pale skinned Andorian pilot was clearly a "pinkskin" type alien when you viewed his neck in this and the previous episode. He was not turned into a blue skinned alien until his helmet was removed at the end of this episode.

Factoids
- This episode features two Reman guards. The Remans were featured for the first and only other time in Star Trek X: Nemesis.
- The drone prototype ship is a modified warbird.
- The Kumari was named after the first ice cutters to circumnavigate Andoria.
- Andorian metabolism is higher than that of humans.
- Antennae take nine months to grow back.
- It would seem given Shran's reaction to losing an antenna, that the antenna are necessary for balance.

Remarkable Scenes
- Archer getting the Andorians and Tellarites to work together.
- Reed saving Trip from the Romulans.
- Reed blowing up a power conduit disabling the Romulan link to the drone ship.
- Archer taking
- Reed: "You're good at building things, I'm good at blowing them up."
- Travis and Hoshi looking for a loophole.
- Archer receiving fighting advice from Hoshi, Gral, and Phlox.
- Archer's fight with Shran.
- Archer cutting off one of Shran's antennae!
- Enterprise battling the drone ship.
- The drone ship performing some crazy maneuvers.
- Trip and Reed diving out of the drone ship so they can be beamed aboard.
- Alliance ships arriving to continue the battle against the drone ship.
- Enterprise rescuing Trip and Reed.
- Trip pulling Reed's leg. Trip's taking out what Archer did to him in Ent: Babel One on Reed. ;)
- The sight of Shran and Gral making up in the end and the joint fleet.

My Review
This episode is one of the best ones shown yet on Enterprise, and certainly one of the most memorable. It's fairly obvious that this episode is supposed to serve as a precursor to the alliance that humans, Vulcans, Andorians, and Tellarites will one day form as the founding members of the Federation and it was done well here. What I liked most was the fight between Archer and Shran. I was thoroughly convinced one of them would die and was pleasantly surprised when Travis and Hoshi found a way for that not to happen. Additionally, I was glad to see Travis and Hoshi play a real role in the story for once as well. Archer cutting off Shran's antenna is of course an homage to TOS: Journey to Babel in which we saw the antenna of a fake Andorian break off, which was nicely clever. The whole incident served as marvelous character development for Shran and Archer. I really like the relationship those two have forged. Besides that, Trip's and Reed's escape from the Romulan drone ship was extremely exciting to watch. I loved how they just dived into space like that, and finally the special effects depicting the arrival and departure of some of the alliance ships were just spectacular. Ent: United is showing us a pattern of writing not present in seasons 1-3. Manny Coto is taking this show exactly where it needs to go, but too little too late. Maybe if we could have had Coto as the showrunner from the beginning, Enterprise would have more than 4 seasons. Season 4 has been excellent so far, but it's too little, too late.
