We have to understand how the extremists got the way they are. Without that kind of understanding we'd never really get to know them. I put in nothing about their childhoods. But what I have put in is stuff about the weird symbiotic relationship between us and them.
One of the things I really love about TV is this symbiotic relationship you can get between the writers and the actors and the characters start to come to life because you start to collaborate.
I've discovered just how symbiotic the relationship is between writers directors and actors. They ask the same questions and strip down texts in exactly the same way.
If a person loves only one other person and is indifferent to all others his love is not love but a symbiotic attachment or an enlarged egotism.
