So you know how after you complete "Oh no! Accidents but different" you get a tape labeled "Riley's Favorite Movies" right? Well once you play it, it starts with footage from the demo/pilot "Episode 1" tape. Well, after you complete that and watch "Summer 19somethingsomething idk I forgot", it starts off with more footage from the demo/pilot's "Episode 1" tape again. And once again, after you complete the puzzle for that tape and watch "Home Movies", there's footage from the demo/pilot's "Episode 2" tape at the very end. So you already know what this entails, right? It means that the demo/pilot is still canon to the Amada the Adventurer story. But how, you may ask? Well, I believe that Aunt Kate is the one we're playing as in the demo/pilot, investigating the original episodes. It would also make sense considering how she knew the tapes were haunted, as hinted at in her note to Riley. Now, you may be asking, how did she write the note to Riley before getting killed? Well, maybe she wrote it before watching "Episode 3" and being brutally killed by the Demonic Entity, as she probably knew her fate before watching the 3rd episode. The only things that destroy this theory is how the tv was upstairs instead of being downstairs like how we see it in the demo/pilot. Anyways, what do you think?
