Interpreting Dylan

To me with the wind "howling" and the wildcat "growling" doesn't produce a positive image to me, so i think the two riders are approaching with sinister intentions. Plus i think that the joker and theif talking are really plotting something. What that it im not sure, but if i had to interpret it i'd say the joker and the theif are the two horseman riding up to the watchtower, to change something, perhaps this is dylan's "transformation" as was noted in class.
