Book 6 Theories

After reading The Forgotten Warrior, many questions have been devised, all of which will be answered in The Last Hope, the long awaited sixth and final book for Omen of the Stars. Who will be ThunderClan's new leader? Why is Onestar always acting so mean? What will happen to Jayfeather after being falsely accused of Flametail's death? So many questions--and NO answers! Here are my theories:

• ThunderClan's new leader: it will not be Brambleclaw, there is a possibility that it would be Lionblaze, but I don't think that will happen. It will probably be a crazy out-of-the-blue choice, like Hollyleaf or Cinderheart
• What will happen to Jayfeather: I don't think anything will happen to him, because it is confirmed that he gets an apprentice in the 6th book.
• What will happen to the Clans: I'm pretty sure they will beat the Dark Forest, but barely. Erin cannot end the series with all the clans dying and having the evil cats take over!
• What will happen to Tigerstar: I think someone will kill him, from ThunderClan or one of his kin. Maybe Tigerstar will be the one to kill Firestar?
