"'This stranger comes for the innocent among us.': Innocence is a quality often given to children.
'The day will come when a stranger arrives in town.': He must not be born in the city.
'This stranger has watched us': It cannot be the newcomer, it must be someone who is in the city for a while.
'This stranger knows us.': He must be close to the population.
'This stranger knows the blessings of the beast that plagues us.': He knows the belssing, so he must be of some faith.
'Death walks with this stranger.': Most likely, he will be the cause of deads.
Now, if we suppose that poem hide some truth, the death of that child must be in relation, and most likely that starnger is someone who hasn't been raised here, and is the follower of some god. I suggets we go talk to the parent of that child who died and learn a bit more about the circumstance of his death, we might know more about that stranger. But I don't expect it will be easy to learn more if Andress is really in relation with that, because she seems to have a good influence on the city, and we are still strangers. If we have the answers we need, I think will have no more reason to delay a visit to Andress, but for now, we have nothing solid enough... I still doubt myself the true implication of Andress in all this."
