Ok, so the whole time I watched it, inside my head the wonderful, little, always baking woman said, "If you are stranded for a year on a distant planet, how would the milk and eggs stay fresh, even if they were in her supplies? They wouldn't even last three weeks probably. Just thought I should tell you."
I love this episode. It is the sweetest thing a mad man and his box. She refers to him as "her thief". The TARDIS was amazing as a human as using her temporary voice to tell him what he means to her. She was smart and brilliant and sweet I love thy she thinks of him stealing her as her stealing him. "I wanted to see the universe so I stole a Time Lord and ran away."
