Spigas was scared to death. His move of trying to take advantage of Andrew upon hearing that he had relations with the royal family and the Caltu family without investigating him thoroughly had put him in a difficult situation.
His greed had led him to seek benefits, but it was his shortsightedness in sending people to kill Andrew when he was rejected that had him scared right now.
Since he ordered his death to the men he hired, he immediately began to investigate Andrew, to see how he would handle the situation after the assassination and then he realized that Andrew was more powerful than he seemed.
Spigas' haste was not only due to his arrogance and greed, but he also thought that Andrew was not very strong, as he only traveled with one guard. Spigas assumed that Andrew who only had Oliver as his protector, looked like the typical rich kid who thinks he can do whatever he wants.
