Despite being a well-known hacker, Solo didn't really take the fact that Interpol was after him seriously.
After all, all these years, he had only undertaken private commissions and most of the money he earned was legal. He had only run to America because—first, he wanted to visit Nora, and second, he found being targeted by Interpol very troublesome.
But even if he was caught, he would be released from jail after just two or three months. Moreover, if he took the initiative to cooperate with Interpol, he could even join them, start out on a clean slate, and become a white hat.
The Interpol had even invited Solo to join them before, but he had declined.
Now that he knew that Brenda was an Interpol officer, he started having thoughts of joining them. That was why he had kept displaying his professionalism just now.
That was why Solo was not afraid at all, despite Aaron subduing him, and was even asking him what was going on.
