Exactly. And thus, between Shaw's inadvertent and probably unwitting shading of the character and your careful analysis and extrapolation of details, a role that was written with only one dimension becomes a three-dimensional collaborative effort. I would imagine Collins' fondness for his character added a similar degree of shading.

It could as easily be argued that there are no one-dimensional characters--that every spear carrier and messenger is as real as the newspaper seller, their reality just hidden from us, waiting to be woken into life by our attention. But I think that would be giving too much credit to their original creators, and not enough to the fanwriters.
