Does the commander *only* poison himself because of time? I've attempted this quest twice now in the last two days, both failing because at some point in the escort back, he died. I need to know *for sure* that its only because we exceeded an hour, *not* because I tried to take him up too steep a hill, or down too far a cliff, etc.

I don't like to give up but this mission is pushing me to the edge.
