"I think I'd win, considering I was once ShadowClan's leader and still have all nine lives. Dusk would be the last to die and Willow would be the first."
It seems the battle was rather recent! Dusk would be last to die, even though she is very old, due to being smart and hiding from the main battle. Raven had defeated everyone around her, but nearly died. She hated killing her brother and sister, but she knew she could always heal them. Raven also managed to defeat Dusk with one last slash to the belly, but she instantly healed the dark gray she-cat.
Thank you for your question, @WindRyder ! ^^
