Talk:How My Grandma Actually Died/@comment-27569420-20160307091125/@comment-31077845-20170302121227

His parents were clearly religious nutjobs, a part of some twisted cultish offshoot of Christianisty or more likely they worshipped something completely different possibly that they made up because they're obviously not entirely right in the head, so they knocked his grandmother out with some kind of medicine and either killed her and buried her or just buried her as an "offering". His mother told him not to follow them or he'd be "left behind". We assume this means they're just going to leave him, but the ending suggests that by "left behind" they meant they were going to kill and/or bury him as well if he followed.

I don't know if I'd call it a wonderful ending, the left behind thing seems like a slightly contrived way to add creepiness, but that was the point anyways.
