On a related note: is there a master plan for Doctor Who?
"It's typical of Moffat that the Doctor decides he's gotten "too big," at the exact same moment that we discover his very name is crucial to the entire universe. And all of this raises the obvious question: How does someone's name become so cosmically important? People tend to be given their names at birth, after all. So either the Doctor's real identity is that of someone whose very existence is problematic."
