After rereading both AGOT and ACOK I was wondering about one question: Why was Hodor not afraid of the crypts under Winterfell at the end of ACOK? In AGOT Hodor was very afraid of the crypts, he wouldn't take Bran down there, but in ACOK he stayed with Bran and Rickon in the crypt for quite a while, how did he stay there if he was so afraid?
Hodor was only afraid of the crypts =at that specific time.= Not before and not after.
