Realization
"You passed."
White spoke as he accepted Deus to be part of their organization, Real Delusion.
White was grateful that Deus didn't kill Green and Red since if he did, he wouldn't have allowed Deus to pass. Instead, White would have done everything he could to kill Deus and label him as Real Delusion's enemy.
White wouldn't allow someone in their organization who wouldn't bat an eye at killing a fellow member. Even if White and the other members of Real Delusion were criminals, it was forbidden for them to attack and kill each other since that was a rule that their boss had told them.
Anyone who failed to do that would be labeled as a traitor of Real Delusion and would be hunted down by the rest of the members. The only circumstance where they could kill a fellow member was when it was within reason such as proving that the other member was a traitor and that claim was backed with evidence.
