Greetings!
The most accurate comparison between Steve's journal and screenplay is: In the journal, he writes in the first person about himself, while in the screenplay, he expresses thoughts in the third person.
His journal is more candid about his feelings, avoiding any mention of crimes or fears, whereas his screenplay reveals a longing for attention that is absent in his real life.
The second passage presents stronger evidence due to including four sources, while the first only offers two.
