For me, the reason Michael was creating the Super Composite Journal was he found himself wrapped up with so many members of this Family. I have even more people in it that not revealed themselves. Not for anyone to read, but for my own sanity...

Nikvodoo's idea that it is Ink reading the journals, I will add to it by saying after Ink reads it, he crosses out "We're Alive" and writes "Were Alive" and chuckles.
