If I recall correctly that's the same book that Bella reading while mentoring Sage (when Sage asked her to read something instead of staring). Well, it was looked the same.
It is the same book. This book was read by Maya, Sage, Bella, Jill, Quinn and the MC. Only Josy I have not seen with the mysterious blue book.
This book also has a logo. This logo reminds me of the logo from the little book with the list of names from the series Arrow. Who knows the series, should think about it.
I just can't help myself. In the Arrow series, the logo is an image of the abandoned Glades subway line. In EP6 DnG it goes down into the sewers. Maybe there is something similar under the B&R site? Or maybe there is a list of names in the blue book where all the family connections are written down? Who knows? But one thing is also strange. When the MC sits in EP2 in the train, a woman is to be seen further back, who reads a blue book.
Which now makes me think of a dramatic, heartbreaking happy ending. What if the woman on the train is Lynette, who is on her way to see Neil because she read something in the book that exonerates Neil in Lynette's eyes. The hotel is being renovated. The MC tells his father not to fall in love with the owner's daughter again. In EP7 Neil really brings a lot and good furniture. The safe is also well filled again. Maybe Lynette herself sent the diary to the MC, that he should maybe understand something, what comes later on him zuukommen. Why Lynette has left him and later in the story it comes to a meeting. Maybe a reunion. Wow. That would be a great story.
