Spoilers: I'm confused about Emma

..it was never explained how Emma's body was found so soon at a isolated area but it must've been Gina as Linda pissed her off by leaving her stranded after she helped bury the body.

It didn't seem very far into the woods so a hiker with a dog could have stumbled on it.

I was rather confused on Linda answering the door and doing jascksh!t while she was ODing on her floor.
