‘Frankly, I don’t think those are real family.’
You don’t think Fuddy is related to her family??
To elaborate. Any theory that requires a vast, hundreds-of-participants conspiracy to work is unrealistic. For example, take the idea that Fuddy is not actually part of her family. That’s an implausible theory. The family did not exist in a vacuum. There were friends, neighbors, relatives, teachers, classmates, church-associates, pediatricians, yearbooks, etc, etc. If the Fuddy’s hadn’t had a daughter named Loretta, we’d know it by now.
This goes for all theories. Once they get too vast and complicated, they’re not viable. A simple conspiracy is workable on certain levels. One that requires too many participants will simply not succeed.
