Do you think that Needle may represent her relationship with who she was, and the Starks, or her relationship with Jon Snow? Instead of Nymeria being the one that brings her back, assuming she comes back, it might actually be a reunion with Jon.
haha, I don't think Nymeria will be bringing Arya back, but that Arya's return back to the Stark identity will converge with Nymeria's return (as a symbolism). Nymeria's return is a correlation, not a causation.
I do think, as you do, that Arya's reunion with Jon will reawaken her moral compass and curb her warpath of vengeance. She loves and respects him, and the Jon she will meet, will be someone who has built his moral character, to earn such respect even more. And I can see his disappointment in who she has become, not anger, not outrage, just sadness and disappointment, prompting her identity crisis.
I think Jon believed in Arya as Arya, her uniqueness, her defiance against the traditional female role, so Jon represents her belief in herself, Arya. Stark will still represent her identity, a loving family who didn't always understand her, but loved her still, completing the picture, Arya Stark.
Oh, that's a good point. That might suggest that the White Walker's end game for humans might be much darker than just murder...
Maybe. It just seems like the formidable enemy, the great Others, need more of a build-up than, 'meh, they just want to kill the human race, and take over the world for themselves, just because.....you know, they're Whitewalkers." If the appreciation of, and hunger for, power, is not explained to at least *some* depth from the Whitewalkers' angle, then it's (1) shallow, and, (2) circular logic.
Doesn't seem like GRRM's MO. That's why the story is fun for me. He weaves tales quite intricately, which is why I like piecing it together. His story is very Ti-driven. I.e., internal consistency is paramount, as is the expansiveness of the connections, tying into one whole. He's definitely Ti/Ne or Ne/Ti. Nothing is left dangling without it *fitting* into something else. [this is an aside, and totally up for debate!]
And, for the Whitewalkers, their motivation must drive their purpose. We kind of see/understand their purpose, but no clue on their motivation. And I can't see it leading to a stale, dead end, of 'just because...' These guys must have a self-driven motive. Now to find out what. They are sentient enough to lead an army, unlike the wights. Otherwise, fearing the Whitewalkers is unsubstantiated. They'd be no different than the mindless wights. There must be something about them to fear, some deeper, darker purpose of theirs.
Maybe.
hopefully.
Maybe the Whitewalker leader, Night's King (name?), that Jon faces off in the last episode is the 13th Night's Watch Lord Commander, turned Whitewalker. Stark-vs-Stark/Lord Commander-vs-Lord Commander face-off. I mean, we don't know if they die like humans do, or can live for a while, like centuries and thousands of years.
EDIT: omg! I just had a thought! Whitewalkers can turn dead humans and animals (horses) into wights! Can you imagine if they turned a killed dragon into one (one of Dany's 3?)? Ice dragon vs Fire Dragon!! Mind. Blown.
Would make for some epic visual animation!!!
Can they turn magical things/people into wights? Oh, the technicalities of Whitewalker's MO.
This was on the DVD set of Season 1, so no unnecessary spoilers. This is a very great introduction - we can dig deeper if you are still curious after watching it.
Just to note, since the video doesn't make it 100% clear: the Starks and other northerners are descended from the First Men, whereas most of Westeros is actually descended from the Andals. This is why the Starks worship the Old Gods and pray to the trees, and everyone else worships the religion of the Andals: The Seven.
Also, the land bridge that the First Men used to cross is at the south of Westeros. The tip of what looks like a boot used to connect, but after being destroyed by the Children all that remained are the Stepstones.

OMG, goldmine!!!! Thanks, U Doggie Dawg! How ridiculous that I didn't even know these clips existed? When that clip finished, I see screencaps of other clips that gives backgrounds on other GoT myths and legends!
Thank you for giving me one more avenue to waste my time with. Mucho appreciated!

4. I still think the spy they captured briefly (the Lannister spy) looks like Tom Cruise. What is this, MI3.5? Besides, he's too pretty to be a spy.
Now I want to find what this guy looks like. Google turned up nothing! I cant' remember this guy/part.
1. The white walkers have been "sleeping " for thousands of years, and now they are waking up. What woke them up? WHy do they sleep vs wake up? I dunno.
Seriously!! People want to know!
