As Virgil explains to Saul what happened behind the diner, he talks about the most disturbing aspect of the whole situation. What does he find the most disturbing?

Virgil says that the most disturbing thing was how cold and detached the men were that abused them in the alley:

“But you know what the scariest thing was, Saul? There was no yelling, no cussing, no
nothing. They did it silently. Like it was an everyday thing. I never knew people could be
that cold."
