Yes, yes, it absolutely makes sense for a goddess who has hidden the info to her own location inside a person with no knowledge on how to access it, kept secret several rites and rituals, locked away stuff in her own library, and gave an expiration date to the knowledge of how to save the world to choose a pathological liar who has to actively try to be truthful about anything over the guy who tries to contain the knowledge on how to create the deadliest non-magical weapons the world has ever seen and is occasionally a bit tight-lipped about his personal business, but is the first one to volunteer to go research things and places they might encounter and become everyone’s tour guide. All of this totally adds up.
