[ it's an answer. it isn't a satisfying one. ]

I don't doubt your skill. But this isn't our universe, let alone our city, and you don't have the resources I'm sure you had once. The person you're going up against can use anything and anyone she needs. She has the money and the standing for it. She may not come at you with physical harm.

You have to consider yourself just as much as you'd consider them. If I can't trust you to do that, I can't trust you to keep me fully informed and there's no point in us trying to work together.
