At the end of their meeting he tells them to go to hell, which ends up being his way of helping them out, as they realize they need to literally go visit the devil in hell to try getting what they need.
While researching to find a way to kill that scraggly-haired bag of evil, Jenny finds a hidden tome which ends up leading the team to a secret cache of old-as-dirt magical weapons left behind by Benjamin Banneker that will help them fight the Horsemen.
