We start by each of you declaring which PC you trust the least.

Um, tricky.  

Anders is a were, and so there will be times that they're a violent beast.  "Even a man who is pure of heart, and says his prayers by night, may become a wolf, when the wolfbane blooms, and the Autumn moon is bright."  Still, Anders-the-human is stable and reliable.  Even the beast is predictable, in its violent way.

January is a different thing.  What can motivate a person who has watched whole civilizations rise and fall?  He has outlived millions of people like me.  What value could he place on one brief mortal life?

So January is the PC I'd trust least.
