The enemy was emerging from the forest, from the east, the northeast, the north; three great columns of heavy horse, all dark glinting steel and bright wool surcoats. Not the men of Eastwatch, those had been no more than a line of scouts. An army. The king? Jon was as confused as the wildlings. Could Robb have returned? Had the boy on the Iron Throne finally bestirred himself?
Robert, Jon thought for one mad moment, remembering poor Owen, but when the trumpets blew again and the knights charged, the name they cried was "Stannis! Stannis! STANNIS!”
The Great Masters had used the pit as a prison. It was large enough to hold five hundred men… and more than ample for two dragons. For how long, though? What will happen when they grow too large for the pit? Will they turn on one another with flame and claw? Will they grow wan and weak, with withered flanks and shrunken wings? Will their fires go out before the end? What sort of mother lets her children rot in darkness?
He could feel the despair all around him. “There must be a hundred thousand,” Satin wailed. “How can we stop so many?” “The Wall will stop them,” Jon heard himself say. He turned and said it again, louder. “The Wall will stop them. The Wall defends itself.” Hollow words, but he needed to say them, almost as much as his brothers needed to hear them. “The chariots, the horsemen, all those fools on foot … what are they going to do to us up here? Any of you ever see a mammoth climb a wall?” He laughed, and Pyp and Owen and half a dozen more laughed with him. “They’re nothing, they’re less use than our straw brothers here, they can’t reach us, they can’t hurt us, and they don’t frighten us, do they?”“NO!” Grenn shouted.“They’re down there and we’re up here,” Jon said, “and so long as we hold the gate they cannot pass. They cannot pass!”
I don’t know if anyone has noticed this but when Ygritte was dying and this shot panned out, the background is split between fire and snow. It looks like the fire is for Ygritte - kissed by fire - and then the ice/snow on the other side is for Jon.
