Would the real Ace ending stand up, please? #DoctorWho

"Which path do you choose?" asks the cover of a book that knows damn well that Ace& #39;s ending is multiple choice at this point.

Anyway I& #39;m not going to top these pictures, so At Childhood& #39;s End thoughts will just go in this thread.

First off, I just need to say, the title is genius. In fact, I& #39;d even say it& #39;s ACE.
