@ jalexbarakarthexists that last part in italics is meant to be like after jack had read it and sees what's written there and also the state of that notebook. something like that ;D
This is a really interesting plot, I've never seen it done before so kudos to you! I am little confused with some things that happened however, I do realize these are meant to be snippets from Alex's life and therefore of course I wouldn't expect it to be long. I'm mainly confused about the end. Did Jack find the notebook years later and was confused by it? Sorry, it is a great story I'm just a bit lost with the ending.
