I have three endings for Hufflepuff boy, seeing as Cayden's are the last one to have a book. And a special.
One: Happy Ending, which is already written but will be rewriting because it is too short and not explained much.
Two: Time Travel, which explains the object that was in Bellatrix LeStrange's vault.
And Three: Dark Ending, where Cayden falls into the darkness that is the Horcrux, and the book doesn't become Cedric and Viktor's fanfic anymore. And explain every interaction with Voldemort that didn't make it into the book because I didn't plan it before hand.
Special: Cayden Potter scenes that didn't make it into the book.
