The Doctor grieving over Amy and Rory was a huge plot point in The Snowmen.
Damn, I'd forgotten that episode existed until now. Really, snowmen. Snowmen.
Can we discuss the line, "you were an excellent doctor. Goodness had nothing to do with it."
I'm rather confused by it and would love to hear all your thoughts.
To echo what everyone else has already said, that's a great line. I see it as him acknowledging the fact that while he's good at what he does, and Clara was good at it, it's not necessarily good in itself. He does what has to be done, regardless of whether it's "good" or not.
