Carl had always suspected there was a problem among the Divine Envoys; otherwise, why would they always be ambushed by Fallen Angels during every expedition?
But it was just a suspicion, without certainty. The possibility of the Human Clan colluding with evil beings was indeed too low, almost negligible. The primary reason for his advance preparations was habit, ensuring he always had an escape route. Guarding against a possible traitor was secondary.
As for Ham… Carl had verified beforehand that there was no problem with him; otherwise, he would not have handed over control of the formation to him. The simplified version of the Twelve Star Gates was also a formation, requiring one person to act as the main controller. Carl had to battle the Fallen Angel and needed to lure the evil beings over, so he naturally couldn't be the one controlling the formation.
"To think that besides Sam, it was you!"
