Warriors: Fire and Ice

Plot hole: When Fireheart takes Cinderpaw out to see the borders for the first time, when they reach the Shadowclan border Cinderpaw says: "I remember that scent from when Brokenstar attacked our camp. And it was on the kits he took, when you brought them home. It's Shadowclan!". Cinderpaw implies that she wasn't one of the kits that was taken, but she actually was. In Into the Wild, when the kits are being rescued, it says: Firepaw helped Greypaw to lift out the rest of the kits. The last one was grey, like the embers of an old fire. She mewled." This kit is female, grey, one of Frostfur's (like all the others that were taken) and is the right age to be Cinderpaw.
