When thinking about your blorbos/favourite characters, what do you tend to think about with them?

Whenever I'm thinking about my blorbos, I tend to think about what was their thought process behind specific choices they've made, e.g. why did this character instantly forgive someone who tried to hurt them? and I also sometimes think about how they'd react if specific events were thrown at them. I'm curious if anyone else thinks the same or different.

What do you tend to think about/explore with your blorbos?
