In the Criminal Minds episode , the "Samaritan Cult House" refers to the base of operations for a twisted vigilante group led by a man named Benjamin David Merva .
The cult used "Rule 34" of the internet (the idea that if something exists, there is porn of it) as a macabre inspiration for their crimes, documenting their "good deeds" and sharing them within their dark web community.
This episode is notable for being part of the larger that spanned the end of Season 13 and the beginning of Season 14, culminating in the kidnapping of Reid and Garcia.
