I sometimes wonder what our reaction will be. It's like Dutta's predicament. When your eyes tell you one thing, and all your memories/thoughts are something else, there is a disconnect. I wonder if we will subconsciously think Naku has changed as a person with her reveal. Will we interpret/read her actions/words differently (e.g. when she talks about her beauty, will we think she is being honest or vain/egotistical).The CVs will have to tread carefully, going to extra pain to make sure her words, actions, everything is what the darker Naku would have. There should be no departure; otherwise, it's going to be a problem.
I may sound naive, but I have full faith in these creatives. What you just wrote here is similar to something I once wrote about the torture track. And they handled it great. It was very well written and acted. I hope the same will happen will the revelation.
