I think I finally understand how people feel with horror movies where the characters act retarded and you're just screaming like NOOOOO lol.
Girl warns the two school friends don't go see the snake infested guy, so they're like OK let's go check him out. The snake dude kills one of them and the girl just sits there paralyzed waiting to die. So far, it's aggravating to the readers but it's fairly believable.
By some miracle the girl is saved from a horrible snake death. Now rather than thank her stars and run for her life out the goddamn house, the girl is like "but what about the other boy that I saw get brutally hurt by the monster". Someone said the characters are believable but I think the main girl is bit too unafraid of death for like a middle schooler.
