Sun Snake:
Maybe even use that to our advantage.
...see what the Drakkar says...
Exactly. I assume we'll be able to tell whether the Drakkar is being honest with his answer (through Sixth Sense).
Thus, if he says he'll play along and genuinely mean it, we'll tell him what information to spread further.
If he says he'll play along, but is lying, we pretend to believe him and deliberately feed him false information.
If he says he won't be helping us in any way, then we just leave him tied up/unconscious somewhere. (Again, we can pretend to discuss our plans in front of him.)
In fact, I hope he decides not to cooperate - be it stated openly or covertly. Then we can be sure of his status. If he agrees to help us, then we can run into problem when his Drakkarim officers don't believe him/interrogate him for the true information, thus stopping to believe anything he says (i.e. not believe any lies we tell the Drakkar). :)
We'll see.
