These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Meaningful Name: Benjamin Franklin Gates; Abigail Chase, likely after America's most famous Founding Mother, Abigail Adams.
Memetic Mutation: "I'm gonna steal the Declaration of Independence."
Nerds Are Sexy: Riley probably elicits this reaction the most in fandom, but Abigail most certainly counts as well.
Magnificent Bastard: The Founding Fathers would've needed to be, considering how spaced out in time many of those individual clues (Liberty Hall, The Declaration and the Silence Dogood letters for example) were made. But they're Freemasons. What else do you expect?
Mitch Wilkinson in National Treasure 2 is the epitome of this trope.
