I triggered the bad ending on 2 different chapters, but it doesn't appear in my gallery. Is that normal? I assumed it was unlockable because I noticed there's a thumbnail version of it in the game's files, but if it's not intended to be viewable in the gallery, that's fair.
Also, I triggered the ending both times while having breakfast with Ian and Oken, and both times, Ian and Oken never left the screen, obscuring the image.
