Ok so right off the bat I know some people are going to be wondering what happened to episode 2. Well the first episode was really a two-parter so that would make the next episode episode 3. Now that that is cleared up lets dive in.
In this episode, written by Rick Berman and Brannon Braga we open up on Hoshi talking to a slug who doesn't feel at home in space. Something that she can relate to, she can't even sleep in her room because the stars don't look right. Meanwhile Archer is anxious to get the mission truly started. He wants to get out and explore. To go and meet new species and see all that the universe has to offer. The two are perfect parallels to each other.
Reed and Trip are both feeling anxious as well. Reed feels that the ship's weapons aren't ready for combat and that they will need them up and running as soon as possible where as Trip feels much the same way as Archer. They both just want to get out and see the universe.
The crew comes across a ship and Archer forces Hoshi to come with him as he goes aboard, leaving Trip behind. Everyone is upset by his choice but he is the captain and that is that. On the ship they find the crew dead. T'Pol tells Archer there is nothing they can do and talks him into leaving. He does but it doesn't set well with him.
He turns the Enterprise around and heads back for the ship. He wants to do something to help them. Trip gets his wish and gets to come on the ship this time. Hoshi is forced to go a second time and decides that she wants to go home. She can't handle this life. She misses Earth.
Reed's fears are proven to be correct when an alien ship shows up as Archer and crew are still on the abandoned ship. The new ship opens fire but Reed isn't ready to return fire yet. His systems are still being fixed up, if only Archer had given him the extra time he needed.
Archer gets back on his ship but their warp is damaged. They fire back but are out matched. A second ship shows up. This one is the same species as the dead crew. Hoshi tries to explain to them what is going on but she is overwhelmed by everything. It is making her work sloppy. Nothing is going the way that Archer would have hoped. He figures out a way to prove they didn't do it but the translator doesn't work. Hoshi has to do it, but her fear cripples her. Archer talks her into it and she saves the day.
All you need is a little faith in yourself, even if you think that you have no chance in hell at pulling something off. Sometimes you might just surprise yourself. Thanks to Hoshi the new ship attacks the ship that was attacking the Enterprise and Reed fixes the ships weapons. They are ready for battle. Well this battle is over but they will be ready for the next one.
Hoshi returns the slug to a planet close to where it was from and tells it that you can adapt. Speaking more about herself than the slug. This episode is clearly really well written and a great follow up to the pilot.
