The restriction array Sam created at the last minute without telling anyone. Well, he created that array to restrict the control of those dark humans over those people who got affected by the nightmare Monsters.
Because of the restriction array, you can say those dark humans even wanted to do something by controlling those humans but unfortunately, they can also feel that the control over those dark monsters became so weak that they would need much more time to get proper control over them.
All the Saints get to know about this today and this makes them sigh in relief. They did not know if they would be able to cover all the strongholds in that short time and what it was during the time those dark humans were already trying to kill those humans or trying to make them do something. Fortunately, after hearing about the restriction array, everyone became happy.
