I think it likely comes down to some people understanding proper writing procedure better than some others. I mean simply typing in "writing inconsistent characters" in Google you get:
"One of the fastest ways to lose your readers and credibility as a writer is to create a story in which the characters are inconsistent."
I recommend learning more about writing practice, even readers have a lot to gain from the knowledge.
Anyway, I'm only reacting to SH's inconsistency the way it's as expected as an audience member in this situation. I have lost my "suspension of disbelief" because the writers did a poor job on act 3. This thread is here because others have also lost this suspension of disbelief. Had they foreshadowed better and done the work to convey her in a consistent manner then this thread wouldn't exist.
