Dario took six of his strongest men with him when he went to speak to the middlemen who came to buy young girls at the club for a job.
Nancy was taken ahead of time, but knowing she could protect herself relaxed Dario a little. The moment they arrived at the Island, Dario recognized the dons involved and knowing he would be exposed, he found a way to send a message to Nancy saying, "expose me."
Having been well-trained but not yet a full-time worker, Nancy understood the assignment. So as soon as she saw Dario with the other bodyguards approaching the Dons, she screamed.
"Salvador's agent. He works for Salvatore. He sold me to you guys, but trust me, he's a spy."
Her voice carried weight, especially when she mentioned that Dario was a spy. Don Ace took the greatest interest and punched Dario in the face.
"I recognize you. You even killed some of my men before."
