[Social Engineering] Hostage Negotiator Style

I have a character who has found the need to learn some "hostage negotiation" skills, for the usual reasons. Pyramid 3/54, "The Civil Arts in GURPS" introduced the concept of "Social Engineering" styles. I could probably work something up for myself, but hey—why not let the community benefit from the resulting discussion? :P

So, what would your Hostage Negotiator style look like?

Side note: I think a Hostage Negotiation Technique would probably not be out-of-the-question here, but to make it a "buy off the penalty" type, there would need to be a penalty to begin with.
