I wanted to make all of the plot points available, because it's a pain to go back through and find them. Obviously, not all questions will be answered until the next part of the game comes out (such as "How old is Aine really?" The narrator remembers her as if she were a child, but the notes claim she was a newborn; or "How did a failing marriage then lead into the couple having Aine?"; or like "Who's Cillian?"), but guesses can probably be made on some things, especially for those detective types. In any case, if you want to see all the clues at once, they're here.

Naturally, be aware that spoilers are possible.

If I missed anything that would be a helpful clue, let me know. I was going based on memory for anything that wasn't a note, and I can't claim to be very perceptive.
