[Costigan has, of course, thought of that. Although he never expected roaming the caves to turn into this kind of golden opportunity, he's spent plenty of time thinking as an undercover and how he could maybe find the same kind of life here, if he wanted to.

You're smart. We both know you could set up some kind of test if you wanted to. We also know that being a good guy is great and all, but incentive helps. Not just money, but- but things you can't get anywhere else. Favors, resources.

It's not like I can run or hide anywhere. If I fuck it up or I lie to you, you'll hunt me down and there's no law that I know of that says that I have to see the outside of a prison for as long as I'm here.

You want to trust me? Try it. I have no fear of failing to- to 'prove' myself to you. You have all the power and you know I've thought of this before. This isn't a bullshit whim.
