David Webb is formerly known as, among other names, Jason Bourne, and currently known as whatever name is on that passport he just showed you. Brainwashed by the CIA into becoming the perfect weapon, he turned out to be slightly defective, which led to him becoming much more defective after he was shot in the back and ended up with amnesia. These days, he just wants to live a relatively quiet life as a decent person who suppresses many of his psychological issues. Unfortunately, his experience makes him doubt this will happen.
