I enjoyed the episode. Sure Hagath was somewhat two dimentional, but who cares? The episode wasn't about him at all. It was about Quark. He was quite clearly on the path to getting everything he wanted, and Gaila was all to happy to give it to him, but it had a price. One that even Quark found himself unwilling to pay. Just proves that sure he's a greedy bastard, but he has a heart of gold under it all if you dig deep enough.
