But I still don't see how, if the arrival post is already in third person (even with a dialogue requirement), then a second third person sample is needed? Both would encapsulate their handle on description and prose, wouldn't they? They'd just be talking about different things, one of which might never come into play during their stay in Taxon.

Again, it's just not clear to me, and of course I'm not trying to nitpick or anything. (: All of this with the greatest respect and politeness.
