From 11:00PM PDT on Friday, July 1 until 5:00AM PDT on Saturday, July 2, the Shmoop engineering elves will be making tweaks and improvements to the site. That means Shmoop will be unavailable for use during that time. Thanks for your patience!
Before leaving for the Wall, Jon goes around with his wolf (Ghost) to say goodbye to his family. Bran is still in a coma; Catelyn still hates him just for being an illegitimate child; Robb seems to have grown in authority (though it probably helps that he's got a giant direwolf, Grey Wind, by his side – most people look more authoritative with wolves); and Arya will miss Jon terribly.
But Jon gives Arya something to remember him by: a sword she names Needle. (Important for later: the sword is light and pointed, like the swords they use in the Free Cities on the other continent.)
