Grey's Anatomy's Biggest Villain Has Been Hiding In Plain Sight Since Season 8

[هَـ-ђāŵĩ-ـَاوِي]

A character who is arguably Grey's Anatomy's biggest villain has been lurking in plain sight as far back as season 8. Grey's Anatomy has had countless polarizing characters throughout its 19-year existence. Given the long-running drama's focus on the world of medicine, things are about to change, since many characters are leaving Grey Sloan Memorial Hospital due to the actions of one individual at the end of Grey's Anatomy season 20. The series has been switching things up in preparation for Grey's Anatomy season 21, but there's a good chance that the characters' current adversary has more scores to settle before the dust settles.
