Washington continues the work started by his parents, who were just as passionate about preserving their heritage as residents of the nation's capital. He is a virtual shut-in at his Capitol Preservation Society. Abraham is a classic social outcast who talks to himself all the time. He has almost no social skills and has a deeper emotional connection to his historical objects than he does to any human being.
As its curator, he is normally seen walking around Capitol Preservation Society rooms and sometimes around other parts nearby. According to Sydney, he asks every traveler who comes through to retrieve the Declaration of Independence.
Washington will mention his Capitol Preservation Society and, when asked about the history of the Declaration of Independence, will tell a humorous inaccurate tale filled with anachronisms, saying that the document was signed at "Fort McHarry" (as opposed to Fort McHenry, which wasn't built until years after the document was signed) in Maryland by the "Second Judgemental Congress" (instead of the Second Continental Congress) and was taken to Britain, by plane instead of ship, to be presented to the king. He also calls the Revolutionary War the "Evolutionary War." His issues with history are understandable, considering the devastation since the Great War that severely limited resources for accurate historical information.
However, Three Dog seems to know more about the document's history.
