Cats of the Clans

 * Rock explains how Brook met the traveling Clan cats on their way back from the sun-drown-place. When she saw Stormfur, she knew he was special, even disregarding the prophecy that was supposedly about him (that was really about Feathertail); and besides that, she could see his courage and skill. When she teaches him how to hunt eagles in the mountains, she grows to love him, for his readiness to try new skills and how he doesn't treat her differently just because she is a Tribe cat. She is close enough to him to share his grief when his sister, Feathertail died.
