Deltora Quest isn't exactly a hot anime among the fansubbing fandom, so DATS is pretty much the only group handling Deltora at the moment. Not to mention they're also boggled down by the main project, Digimon Savers and another one, Ryuusei no Rockman, so Episode 1 by DATS is pretty much the only non-Japanese release so far.
And Deltora Quest is not yet licensed for release in English by any company.
Anyway, the Episode 4 and 5 are a little more boring than Episode 1,2,3, but I'll surmise that to the general minor "things" that goes on in novels. Since Deltora IS a book-based anime that apparently has a high degree of faithfulness, I'd expect some episodes like that once in a while.
Episode 6 = Jasmine in a hot-tub?
