Amy and Eleven and Vincent holding hands as the sky explodes into a starry, starry night. Vincent getting shown around the TARDIS, while Eleven and Amy dance a little waltz--and that was the little girl's design who won the Blue Peter contest and they didn't just toss it in as a throwaway reference, they highlighted it and made it something truly special for her and for the audience. Eleven, in the fez (RIP), telling River, "Hi honey, I'm home." Rory in Venice: "The only thing uglier than you is--is--your mum!" Hot evil Eleven/Rosanna UST. Eleven in mutual flirtation with a Bill Nighy character because apparently Moffat and Richard Curtis love me and wish me to be happy. The Doctor's subconscious shadow-self revealed to be an evil Truman Capote. Nasreen! Liz X meeting River Song after she gets a phone call in prison in the fifty-first century from Winston Churchill in the twentieth because Churchill's robot scientific adviser found a lost Van Gogh painting in the best intra-show cracky crossover ever. Amy's tiny little dad. Rory the Roman. Amy "flying" outside the TARDIS. "Fish fingers and custard--that's what Tiggers like!" The bedside monologue in "The Big Bang." I could go on, a lot, so I'll stop here. :-D
