His Fault.. All was his Fault. When you got to be David's age, almost all that went on in the world could be called your fault. Especially when you have a ghostly hand in all the goings on of the world. But Haythem Kenway.. that was his fault for sure. Had he been quicker in saving Edward Kenway's life.. or had he not given Haythem the advice to join the brotherhood, maybe this would not be happening.. yet of course it was, and David needed to rectify his own mistake.
So David was in Boston, the last known location of Kenway. The Ghost Assassin wondered what he would find as he disembarked from the Normandy, his hood up as always.
