Interrogation

Sarah Harley stared at the young man.

("That made sense," she thought.)

She had already anticipated that he would ask for something in return, so she took the initiative:

"An exchange? Why would I negotiate with you? What do I gain from it?"

Sirius frowned.

("This woman..." he thought.)

He had already provided enough to strike a deal.

("Cops... stubborn to the end.")

"I'm offering you priceless information on a silver platter, information you never would've gotten without me."

Sarah laughed.

"Without you? You're not the only witness. Your sister, or your friend, could've helped us too."

"Are you so sure? You clearly don't know them well. My sister Iris is someone even you couldn't handle. She'd make you question why you do this job. You'd walk away knowing less than you do now.
