At first, the Journal of Facts was scared by the fact it had been unable to prevent Jane from writing it would be destroyed, but thankfully that part didn't get any related illustration and, being written as a new paragraph, the Journal could dismiss it as not related to the story.
Now, it just needed to find a crack into the goddess' mind and… Ah here it is.
Being a 12th dimensional creature, (a.k.a. a goddess) Faith can see and feel things no human can, as silly 4th dimensional being. (Yep 4th, three ‘spatial dimensions’, sometimes called material dimensions, and one for time.) That's what the concept of a being that's a part of someone-else while simultaneously being themselves is so hard to understand, even for humans having an angel.
The same kind of logic apply to feelings. For most humans, friendship and romantic love are mutually exclusive. Not only that, but they tend to see romance as something more than most other kind of love, like it was some sort of ‘upgrade’ or something. And that's why Faith was unwilling to reveal all her feelings for Colin, because he is human, and as such he probably won't be able to become her lover without stopping being her friend.
And that emotional turmoil was all the Journal of Fact needed to be able to manipulate the goddess.
It made Faith cross-out the paragraph about the goddess destroying the evil Journal. Said book might have tried to continue using the goddess, but feared said goddess might take back control of herself and find new way to destroy it, if not doing something it would find even worst, decided to disappear and find itself a new master.

Louis was an average teenager and, unknown to the Journal of Facts, one of Colin's friend. As his name suggest, he is a latino boy.
Finding this strange and old looking book, apparently titled "Journal of Facts", Louis decided to open it an observe its content. On the first page, in illuminated script like one would expect in an old bible, he found the following text:
"To whom it may concern: You have purchased The Journal of Fact. This is a powerful artifact that can alter reality itself. Whatever written down will become the truth.
If something already being the truth is written, nothing will happen. But if a lie is written reality will change, turning that lie into fact. Anything written can be erased but if that same thing is written a second time it will alter the writers mind, making him also believe it to always have been the truth. If someone else other then the owner writes in the book, the writer will still be the only one aware of the changes.
Use this power wisely."
Louis would have believed this to be a joke, a rather bad-tasting one at that, it it wasn't for what he found on the next page. You see, whoever created the Journal of Fact believed it would only be used by writing in it, never expecting someone would draw to illustrate what they wrote. Thus, while anything else written during Colin's ownership of the Journal had disappeared from its pages (but stayed true), what Jane wrote and draw simultaneously did and didn't count as being written two times.
Because of that strange quantum state, while everyone believed the ‘story’ written by the young starlet had always been true, the Journal would forever hold the proof it wasn't so, clearly visible for all subsequent owners of the Journal of Facts.
And while Louis understood what Jane wanted to accomplish, he found the way she came about it boring. But he was the new owner of the Journal, maybe if he wrote after the young starlet's story, saying that things happened differently, it would alter her story accordingly?
