"I'd have to agree with Veryon on this. It seems like a bad plan. We're better off just attacking. If something goes wrong while you're in there, I doubt you could fight them off alone. The risk of your idea outweighs whatever information you might manage to gather, if there's anything even worth knowing. Knowing the layout isn't worth very much either, and I doubt you would uncover any secret rooms or the like. Plus even if it succeeds, even if you somehow find out about the organization these people belong to, then what? We can't just leave them. They're extorting the populace. Either way we're going to have to fight, but we may as well do it now instead of sit on our haunches and hope that your incredibly risky plan succeeds. So then, as I said earlier, let's just rush in, and do what each of us does best. Thirodaen, if you would be so kind as to start picking off those guards, I would appreciate it. I am going in. Its about time to get this over with." 

Whether or not Thirodaen starts shooting or anyone follows him, Nicholas begins headed towards the gates. Something is clearly going on inside, and the longer they delay, the higher the possibility more people might get hurt. They have no time to stand around bickering, and he will fight his way in alone if he has to, but he hopes that the rest of the mercenaries join.
