Gotta go with Ben Franklin and how they treated him in AC3. He shows up to ask Haytham to find his book pages, dissappears, comes back for one cutscene, and then dissappears. Like, he didn't even ask Connor to find his pages.
But to go back to AC3, let's look at how they showed the Sons of Liberty in that game. They stripped back a lot of the terror that group did prior to the revolution, such as tarring and feathering merchants or other Loyalist figures in Boston. Did the SoL's activities aid in galvanizing the colonists against the crown? Yes, of course. Is AC a piece of historical fiction that requires "good" guys and "bad" guys for you to protect or kill? Totally, but the closest we get to a character questioning the Sam Adams and the SoL is when Connor addresses slavery and how that group had no desire in freeing slaves while equating themselves to the same situation.
And then it gets dropped in favor of running around Boston with Stephan and the other recruits. The SoL also get treated like a little boys group by Connor when he gets the message from Paul Revere about Pitcairn. So not really an individual, but more like an entire misrepresented group. How fun would it have been if Sam or Paul were secret Templars, used by Charles or Haytham to conduct the Massacre and the Tea Party to instigate the war? It feels like a missed opportunity.
