Despite the generally cheerful atmosphere of the Thousand Sunny and the normally high spirits of its unusual and rather eclectic crew, the Straw Hat pirates can't escape their pasts. Each of them brings to the ship a lifetime of memories both pleasant and unfortunate and, although many of them would prefer to think otherwise, he or she carries an inescapable barrage of personal emotional baggage that rises to the surface when least expected.
They move on - it's what they do best, and they cannot afford to hesitate, not with the World Government's steadily-increasing bounties on their heads or the constant perils of the Grand Line - but their fears and failures move right along with them. And while they try not to dwell on their shortcomings and their losses, human nature dictates otherwise and sometimes all it takes is a glance, a word, a gesture, for those deeply buried insecurities to come creeping back.
