Every year he stopped by the grave to share his secrets. Dead men tell no tales, supposedly. Although, the way everything was progressing they would soon be able to enact their own version of bringing Wesley back from the dead ala Princess Bride. He would bring his empty jar to the gravesite and then fill it up with his secrets and lies.

He would then take that jar that appears empty to everyone but those highly in tune with the universe and place it on his mantle. Visitors would look at the jar and wonder if he was going to fill it with something as it appeared non-remarkable to everyone. Yet, he would just smile and nod. Everyday, the jar was lighter as the secrets evaporated over time.  But this could be the trap.
