On the surface this was an entertaining episode. We see some character progress on Hoshi, who with help from T'Pol learns to control her anxiety and becomes more decisive, later deciding to fire the torpedos that (apparently) saved their lives.
Besides that, however, there is not much happening in this episode, and some of the things don't make much sense. Considering that even my notebook is password protected, I find it awkward that both humans and Klingon can so easily access other species technology. And if Hoshi had all that trouble to understand Klingon stations and commands, one might assume that the Klingon (which never heard of humans) might have had some too.
Going beyond that, however, Archer as always brings tons of eye rolls. His speech to the Klingon is horrible, and after his so-called "Klingon research" (shouldn't he had done this *before* becoming a starship captain?), he basically just say the same BS but now with inserting a "honor" somewhere in the middle. But I guess that was the safe-word, since the Klingon woman suddenly just go against all her previous arguments and any common (Klingon) sense and accepts her help. It is still not clear what keeps Archer from stunning her and stealing their technology (and hell, anyone less dumb than Archer would immediately see how hugely important opportunity this would be), and I'm not completely convinced that having another species board your ship and drive your sleeping sick bodies to safety is more honourable than just dying, but I guess she found it so.
And finally, I don't quite understand why they even needed her. If the pod was able to go back to the ship in the end (wasn't this the entire problem?), why did they even take her? Just go there and take the people back. But no, Archer has always to be the Big Hero, even when no one wants his help and risking his crew for nothing. At this point I just wished the Klingon battleships would arrive and make him pay for his annoying stupidity.
And I guess this is the great shortcoming of this show so far. Archer behaves with absurd stupidity, but even though he is supposedly in a very dangerous space which he knows nothing, he is never punished by it. Everything always works out all right.
