I can see a Jimmy Kimmel or Jay Leno bit on this.
While the USA has it's share of idiots, I think the majority of "ignorance" about international geography that foreigners complain about could be better described as "not giving a shit". I have a lot of foreign friends and know tons of people living overseas and they love to say stuff like "We know where the USA is and who your president is and blahblahblah but you don't know any of that about my country. Americans are so ignorant." Why the fuck should we care where your little country is located or who the meaningless leader is? I don't mean to belittle other countries, but the fact of the matter is that in the grand scheme of the world--especially from an American point of view--90% of the countries don't matter, whereas whatever the USA does has a huge and direct affect on most of the rest of the world. Obviously more foreigners are going to know about the USA than visa-versa.
Ghost abandoned Jon Snow before he went with the Wildlings, when Jon was messing with the redhead. Samwell was the last to see Ghost in Episode 1 or 2 of this season in the distance if I recall.
GRRM is going to write a "Direwolf Trilogy" talking about the adventures of the direwolves over the course of the 6 books when they were otherwise off screen once book 6 is done. I'm sure it will only delay book 7 by 10-12 years.
We will have one of those 6 books be a two parter where we only see one of two wolf's POV also.
If I remember correctly ghost was with him until he climbed the wall in the book. On the show he left before he killed qhorin.
