Status Updates From A Most Peculiar Providence

So much wrong with this story. I keep waiting for Jaime Jo Wright plot twist & for Mama's body to be found mummified in the basement when Josh finally reveals his true colors & ties Heather up. Totally not what's going on in this story, nor do I expect that, but the whole "Mama" obsession pings my creeper radar. If he's not autistic or otherwise dependant, then what's the deal? Creepy vibes. Totally.
