It's moments like this that break my heart. I mean, when you think about everything he had lost. A wife, children, parents, grandparents? Family. All gone. But, now that we have the possibility of finding Gallifrey, it could be fixed. <<< This comment right here gives me hope that the Doctor will find Gallifrey and free them all.
The Doctor quoted Mary Poppins!! Well, that makes sense since she's also a time lord...has the 'bigger on the inside bag', goes where she is truly needed, she travels to odd places, has companions, AND has a British accent- sounds like a Time Lord to me!
