My PSR tells me that for the OS, act one deals with Developing a Plan, explored in terms of Closure, Hope, Dream and Denial.
That quad (Closure, Hope, Dream, Denial) is in Fixed Attitude>>Innermost Desires, and is also labeled MC Benchmark, Forewarnings.
So does the shift you mention reflect some relation between the different throughlines?
What does it mean to associate a set of variations and elements with a type, generally speaking? I am guessing it has to do somehow with the (twisted and biased, as you say) perspective that the characters in a given throughline have on the inequity. Is that correct?
