I thought the augment arc was three episodes but whatever, even one would have been too much in this case. I actually groaned when I watched it for the first time.
There's the augment arc(The the orions and then Cold Station and their attempt to murder a Klingon colony...) , and then the follow-up arc with the Klingons (Featuring Phlox getting kidnapped, and Enterprise almost blowing up, and yadda yadda...) .
So it was really five episodes, three helping to build up the background for the events that followed in the other two.
