Before the Mafia boss, José, set out for Milan with Yuri, he had mandated Gerardo to check out the Pero guy—a mission Gerardo was particularly enthusiastic about, since it would have been Yuri's 'Call of Duty' if he had stayed behind.
He had the place scouted out, before setting himself by the corner watchful of anyone who would come around. While, the others stayed inside, he had the door locked from outside.
Gerardo was given specific instructions to keep Pero hanging for an hour or more, even though Gerardo was always impatient, he managed to do as he was told. He saw Pero make an entrance, he watched him curse and spit a couple of times. Then, knowing that he was about to take his leave, Gerardo decided to teach him some manners.
