5. The Speaker For The Dead
At the end of the novel, Ender decides to leave Eros with Valentine, and take the first shuttle that will transport humans to the Bugger worlds for colonisation. Once there, Ender becomes governor of the colony, and helps it grow and flourish. After some time, Ender goes on a scouting mission across the planet in search for more land for a second settlement. He comes across a place that the Buggers left for him, after reading his mind at the Battle School, and in that place he finds a cocoon, which houses the last Bugger Hive Queen in existence. Ender speaks with the Hive Queen telepathically, and begins to understand the true nature of the Buggers. Still heartbroken from his recent act of xenocide, Ender promises to take the Hive Queen with him and someday restore her and her species. He and Valentine leave the colony, and on their voyage to the next planet Ender writes 'The Hive Queen and the Hegemon,' which tells the true stories of The Buggers and his brother Peter. The book becomes legendary throughout the galaxy, and eventually forms a new, humanist religion and reshapes the way humans view their victory over the Buggers. Ender signs the book 'Speaker for the Dead,' which becomes important in future novels.
Why We Probably Won't See It In The Movie: Though it's only the last chapter of the book, Ender's time on the colony and eventual meeting of the Hive Queen would take a
lot of screentime, involve too much exposition, and ultimately leave strands for a sequel that is more unfilmable than Ender's Game. Though I do think that
some of the final chapter will be in the film, I doubt we will feel the full effect that it has on Ender, and on the rest of humanity, for that matter.
