This one is really weird and hard to make out so this is what I think it is.
Obviously this one is drawn in blue marker.
A stark difference from the grey and blacks of other pages.
From what I can tell the words from left to right are
"wrong" "why" "help"
The drawing in the middle to me is a spire, drawn very badly.
I assume he didn't like it and that's why he scribbled it out.
Here's the thing,
the next 12 or so pages are all scribbles in the same blue.
I didn't want to take the time to scan all of them,
so this one will have to do.
Here is what those pages are like though, for continuity.
They begin with large, page filling scribbles.
As you flip through them they get smaller and smaller.
The final page is just a single dot on the page.
To me they could mean one of two things.
Either they are an angry outburst, like he wanted to hurt the book.
Or, and to me this seems more likely to me,
this is a strange type of spire in the dark place, a blue one.
It's like some kind of flip book animation. I know he made those before.
To me it's like we arrived at this strange spire and we are moving away from it.
Based on the page to follow it seems like this may have been a bright spot.
Soon to be left behind.
