The Hive (Within The Honeycomb)

Following a psychotic break Jerry experienced caused by both his failing marriage and increasing distaste for his wife accompanied by her fascination with her father Rick, he took Morty and Summer without a proper custody agreement and fled off the radar, wiping everything he had to his name and abandoning all devices.

Abruptly choosing to form a fully fledged religious group referring by the name of 'The Hive', his personality morphed into something polar opposite and forced Morty and his sister to comply with it as they are beaten down to a shell of themselves and succumbing to the organization.

Rick is still avidly searching for his grandchildren while Beth attempts to work with the police in the hunt, both unable to track either of them and are unaware of the secret formation the children were placed into. As little as Rick values Earth's officials, he appreciates his daughter's assistance in recovering them. He wouldn't stop looking that easily.

If Jerry was still somewhere on the planet, which he was, there was no way in hell he would give it up.
