“There's nothing like a mission to save the world to liven up a vacation.”
“My mission is to kill the bad guy, save the world, and hopefully end up with the girl. (Steele)”
“...maybe the world needs a cadre of smartasses to liven things up, who knows?”
“There's nothing more dangerous in this existence than a moron on a mission.”
“If nothing matters, there's nothing to save.”
“When there's nothing left to save, there's nothing left to lose.”
