Bang and the others' attention were solely on Lily as she said those words. This was the reason why they wanted to socialize with her in the first place.
If they knew why Lily and her group wanted to go with this plan, if it was something that was not beneficial to Bang and his group, then they would opt out of the plan.
Bang leaned forward as he patiently waited for Lily's next words. Lily seemed to know that Bang and his group waited for her reaction, so she paused for dramatic effect.
After a moment of silence, the tension kept building up. Strangely, the prisoners seemed to not have heard anything from Lily's mouth.
"Well, we are here because we wanted to retrieve something. You know what it is, right?"
Lily looked directly at Bang, clearly directing her words at him. Bang was speechless at her words. He did not actually know about their backstory, so he did not know what she was talking about.
