You know very well why you're suspicious right now.
You invited the D to defend one of Melo or JBF. Why did you do it? Was Melo investigated? Was JBF? If one of them was, then the Gs know that he was investigated and made it a battle between those two in order the D to come and save the investigated person.
The D seems not to have came and you asked him to come and defend one of JBF or Melo. You asked him to do what the Gs are waiting the D to do.
