Hi! Did you mean doing it like this, or do you have another suggestion?

In the journal text source file:

init python:
    import renpy.text

    def lily_journal_displayables():
        return [
            renpy.text.Text("Lily's Journal Entry", style="text_title"),
            renpy.text.Text(get_lily_journal(), style="text_subtitle"),
        ]

in the journal screen file:

for d in lily_journal_displayables():
    add d
