Saint John and the others already begin to check all the gifts that Sam has already given them. Saint Markus also informs Sam that they already selected those places which would be turned into strongholds.
When they previously discussed this they also already prepared the team of Warriors who were just waiting for their orders to immediately evacuate those places and make those places ready.
Well, Sam also told everyone that they should not reveal the secret of those arrays to anyone other than themselves as this could be dangerous. He told everyone that he had a method that would be able to prevent those people from other planets from entering the strongholds.
Because of this, he doesn't want those people from other planets to get to know about the method. Naturally, everyone also agreed with that and with these, they did not decide to reveal any kind of secret about those arrays.
