"Hey Alex, did you make sure that your sister won't find out about this?" Cooper inquired in a hushed tone.
While hearing him, Alex nodded confidently.
"Don't worry, Cooper. I made sure that big sis won't find out about that we are going to an auction," he replied, making Cooper, Nolan, and Jose feel relieved.
The auction they were attending wasn't a normal one. It was on the line between legal and illegal, which was why they were worried.
If Karina found out about them taking Alex to such a place, they wouldn't be able to live. As for why they were still taking him because Alex found about their plan and requested to tag along.
Of course, Cooper and the others were initially unwilling to take him because of his sister Karina, who was a brother-con. Nevertheless, they agreed, as Alex was a friend, and as long as he doesn't buy anything shady, they didn't think it would create any problems.
