What amazes me about the characters is how many of them are Attractors or Mentors, or at least have the potential to be.
Chuckie, Sean, Lambeau, Skylar, all the way down to the CIA guys in their one scene - everyone wants to form or continue a relationship of some kind with Will (lover, friend, teacher, employer) and we can see how that relationship would shape Will, for good or bad, if he were to commit to it.
No wonder Will's so confused - he's surrounded by conflicting patterns on which to shape his life, each embodied in a character, and all of them have something to recommend them.
The other thing about the characters is just how damn well written they are! Just like Will, none of the significant characters are exactly what they seem. Everyone has hidden depths, concealed pain, secret motives. Just when you think you know what a character's doing in this story, they surprise you. Best example, maybe, is Chuckie - who may not have much in the way of smarts, but who turns out to know what Will needs better than Will ever has.
