Um, plot holes, anybody?

Did anybody else wonder why Richard and Kahlan never even seemed to consider other uses for that collar if it could really block Kahlan's powers? Let's see... Richard and Kahlan can't be together because of Kahlan's powers... there's a device (that is apparently one of many) that can suppress Kahlan's powers only while she's wearing it... so let's use it to keep Kahlan from confessing some enemy soldiers and then just toss it aside!
Of course, the last time they found something that would let them be together they gave it away, too... I'm starting to think the maybe they really don't want to sleep together.
And does it really take just an afternoon to conquer a kingdom? Didn't that city have walls? Why on earth were the (arguably) two most powerful fighters in the city not up on those walls helping to defend it instead of sitting in the throne room waiting for everything to hit the fan?

I do like the show, but I really feel like this episode just fell flat on its face.
