User blog comment:Dorkpool/A Few Words on "Squidward's Suicide," "Dead Bart," and Lost Episode Stories in General/@comment-5101683-20190906080307

The best thing about this is that the person who claims to have authored Squidward's Suicide wrote, "I had just read Suicide Mouse and Dead Bart earlier that night," in a Reddit post about writing the story. (The writer did it here). So you were spot on.
