There was a meeting other "refugees" orchestrated. There's a device that jams their signal in here.

[before Hisoka's time, he's saying without saying. there's so much he could tell him about that meeting, but not all at once. not unless he asks.]

It's not exactly convenient, but it means people can talk freely.

[folding his hands, he puts them on his lap, never letting his eyes leave Hisoka's face.]

How much do you know about this place? The colony in general.
