Jason's point of view. Word: Blank.
There were so many blank spaces in his life that sometimes he felt as though the only defining quality about his identity was his complete lack of one. He did not know who his parents, siblings, friends were or where they lived, if they did. He did not even know his own age, his own birthday. He merely existed, a man named Jason Bourne who had a bank account in Zurich filled with millions of unexplained dollars, seven different passports, two cases of colored contacts, and a gun.
The blanks threatened to overwhelm him as he scrambled desperately for answers.
