Kody sure misunderstood the burning bridge question--TWICE!
First time, he shows NO enthusiasm to rescue his wife who is about to die on a burning bride. Cue other 3 wives to tell him, "If there was a human there, would you rescue him/her?" while Mari looks on with dagger eyes.
THEN he brings it up for a second wack at it and swings and misses. He thinks that his and Mari's relationship is "the burning bridge," and says, "It is not on fire, we're doing fine."
