The kit wakes up 2 days later, in Leafflower's den. Shiverkit declares him her adoptive brother, and Heatherkit rolls his eyes. They ask about the kitten's past, and he says he doesn't remember. Shiverkit describes him as ice-colored, and says he looks frozen.

The kitten has no choice but to stay in the Clan, so Sagestar gives him the name Frozenkit. He quickly becomes friends with Shiverkit, his adoptive sister, and Heatherkit, his best friend.

Shiverpaw and Heatherpaw become apprentices, while Frozenkit is a kit for another moon. Amberpaw keeps him company, much to his liking.
