That post was utterly fascinating. It is an interesting twist if a strength in one situation can be a weakness in another. I thought of an example. Christian Grey is my favorite character in the 50 Shades of Grey trilogy, by E. L. James. He has an amazing character arc. He starts out as being one with a lot of ambition and control. The article quote at the top fits him very well. I have never seen Ms. Congeniality, but your description reminds me of him. Christian’s strengths are being hugely successful at business management and filthy rich. His major quirk is the bondage fetish, that many fans talk about. Christian’s story began when he meets Anastasia Steele, the protagonist. He was attracted to her, so he tried to court her. He was so controlling and cold, that he temporarily drove her away. Then Christian had to learn and change as a dynamic character. He learned that his ways needed to be tempered with kindness and love. He becomes a more balanced. Although he remains wealthy, he was caring and protective for his new family. (but not overprotective)

“One key factor we must appreciate is that every strength has a flaw.”

I came up with the same conclusion, while studying psychology. I am particularly fascinated with personality. Eventually I read the main book for the Enneagram. It was such a good read, I devoured it. The interesting part I come for is the variety of nine types. Each type has strengths especially with a healthy balance. Each type also has a weakness, especially when unbalanced. When the weakness is powerful enough, it leads to insanity. This is a darkness that I am not used to. But I stayed for it, and it helped me make mind-blowing insights of the psyche. In a nutshell, I understood that a healthy and sane person has all personality traits to some extent. That doesn’t mean such person is perfect. This brings an interesting interpretation to Christian. His Enneagram type is 8. In a worst case scenario, he could turn into a sociopath. I don’t think he ever goes that far, but he was still very bad. Over the course of the story, Christian develops into a healthier state, while retaining the strengths of his type. I can imagine how this could expand. Characters of all types, could go through the journey of balance. I can even match the examples of the article to types. A strong leader is an 8 of course. A loyal person is a 6. A tender-hearted person is a 2.
