The next question Jack would probably ask would be in regards to Global Spiral, as he at least has that name to go off of when it comes to the Gates kidnapping incident. He'd want to know if this guy is aware of the group, if he knows who usually hires them (does Riverstone?) or what kinds of jobs they generally do, etc. etc.

If the contact wanted to know why he was asking all this, Jack would explain that the Displaced as a group had some interaction with Global Spiral, but wouldn't really want to say more than that, citing that it wasn't his place to speak for the Displaced as a whole. He would imply that he'd had a run-in with them that he wasn't too thrilled about, but wouldn't go so far as to allude to kidnapping or anything like that.
