Hrm, his answer wasn't "what would honor pick as its best match," it was, "which shard would be most likely to take odium." So, Dominion might be closer to Honor. Honor is incredibly subjective, however. The Alethi honor those who kill. If you asked the Shin, they'd likely say Honor was closest to Cultivation, since they revere farmers. A Windrunner might say Honor is closest to Preservation, the ultimate protector.
