That TARDIS/Amy comparison is fascinating. Plus, they both have extraordinary abilities of memory: Amy can remember things that never happened, and the TARID can archive things that haven't happened yet : )
Your point about knitting is forcing me to remember when it first came up in TIA, when the Doctor was trying to run away from the "mysterious summons" to investigate the astronaut girl (his future). He, all unwittingly, tried to send them off to their already-determined fates. Amy and Rory were "off you pop and make babies." River was "back to prison," symbol of her status as his wife and killer. And for himself? He proposed "knitting or biplane lessons."
Re: verbal diarrhea time! Really, that was a lovely analysis!
