The Night's Watch expedition beyond the wall rocks up at Craster's house. Craster is an off-grid homesteader, except that he kills all the boys and has sex with his daughters, so it's just him and his wife-daughter-neice-granddaughter-cousins. I'm starting to get that incest is a bit of a GRRM theme. In return for a nice axe and a crossbow, Mormont gets Craster to tell Sam how to draw a map of where Mance Rayder the raider is these days. Sam sends one of Craster's daughter-wives to Jon for help escaping, but Jon can't help her.
Mormont says Craster has to give the boys to his "cruel gods". I think it's probably the Others.
