Archer was wrong to steal from and strand the Illyrians. I do not believe the ends justify the means. However, with Earth and humanity in the balance, and Archer needing to fix his ship's warp drive, he made committed piracy to continue his mission. When the Illyrians Captain was explaining that Archer is standing them far from home, Archer could have given some optimism, we'll come looking for you when this is over, take you home ourselves if we have to.
As it is, sometimes our Star Trek characters do horrible things in the name of survival, giving us the occasional dark episode. I just wanted a follow up episode given UPN was allowing the show to be serialized now.
I'm going to go the other way.
Archer was an embarrassingly shitty Pirate.
The Captain (or the MACOs) should have had the tactical experience to take that coil without loss of life, fucking around, or even a conversation.
Suggestions.
1. Beam in Stun grenades or sleeping gas.
2. Beam out the engine parts .
3. Wait until the night shift, when most of the ship is asleep.
4. Beam the enemy crew out of their ship, until its a ghost ship, and they are all held securely on Enterprise.
5. Take hostages.
6. Take the Captain Hostage.
7. Force a surrender by pummeling their ship with torpedoes.
8. trick the entire crew into going down to a secret moon for shore leave, then take the ship for "Captain Tucker".
9. Brainwash the Captain with drugs or a mind meld, into handing over the coils without a fight.
10. Kill them all, and take what you need, over their corpses.
