-Dungeon/ secret rooms "within the walls thus exposed by the displacing of the bones, we perceived a still interior crypt or recess... for no special use..." This is showing the grave Montressor made Fortunato
-Emotionally cut off from people "You are rich, respected, admired, beloved; you are happy as once was I" this is showing Montressor has no friends but at one point did whilst also being respected and admired which he currently is not
-Heightened sense of drama "For half a century no mortal has disturbed them. In pace requiscat (rest in peace).  This quote means that Montressor ended up killing Fortunato
-Ominous implications precede dark events "No answer still. I thrust a torch through the remaining aperture and let it fall within. There came forth in return only jingling bells."  This is showing that
-overall impression of decay in a character "Against the new masonry I re-erected the old rampart of bones"  Showing that Fortunato decayed into bones almost a half of a century after Montressor murdered him with impunity.
-There may be unexplained manifestations "He again took my arm and we proceeded." This shows but doesnt explain that Fortunato is drunk out of his mind so badly he can hardly walk so he will easily fall for Montressors plan.
