(Try to guess the father...!) I have an idea that in the future, Blizzard will have a mate, and eventually, kits. By this point, Blizzard had seen enough to know that BloodClan wasn't the best place to raise kits. Warriors would viciously maul kittens around the ages of three-to-four moons, in attempt to "train" Them. Many kits already had many scars dotting their pelts at the tender age of six, technecally old enough to only START training in an actual clan.
