I am surprised that doesnt include the bit about Maise (right-handed) insisting on learning the swordfighting scenes left-handed because Arya is a lefty in canon.
I think they had to add more for Dany so showfriends wont forget about her/complain. And I laughed at Dany being in "friendship is magic land" because in ways it is a little true, shes an idealist. But this also implies she is soft, and easily pushed around because of this. Just wait, her story has barely started.
It's too bad they had to age up Sansa for the show, she was 13 or so in the books, so her naive swooning after Joffrey and the ease with which she is manipulated makes a lot more sense. She does seem rather dumb currently cause you expect her age to show more maturity.
