I think the show heavily implies that he can teleport. It hinted at something like that through his swiftness when killing the dude after A Girl Told A Man When He Must Do A Thing, but it was only after he was standing on top of a cliff then appeared next to Arya seconds later that I figured it was true. Others say it's just because he's slick as fuck, which does make more sense according to the story, but the editing of the scenes belies that unless he's got like Nightcrawler speed. How else did a dude in like sixty pounds of armor/weaponry silently climb down a 20 foot cliff in like three seconds? I guess we'll find out
Yes the Walkers and Wights are different. Not yet sure which is exactly which though. The cloaked ones from early on are Walkers, the undead that Snow burned is a Wight, it is assumed that the horde of walking zombies are Wights while Old Man Winter on horse is a Walker (uncloaked), and I'm not sure what the dude with axe who got Ghost'd is (blue eyes, I thought only Walkers had blue eyes...)
How do you not remember inside boob?
