Okay so

In Code of the Clans, there's a kit named Smallkit and some other kits. They drown, but then when they're in StarClan Smallkit's a leader and the other two kits are warriors. How does that work?

I think it says something about Smallkit living long enough to be leader or something like that. Uh, hello! He's a KIT. He didn't even live long enough to be an apprentice!

So, if there's anyone out there who understands the whole Smallstar thing, please explain it to me.
