I get a lot of entertainment out of speculating and mocking both Kat and Seth but at the end of all of this, many lives are ruined.
Lizzie is gone and may she rest in peace. Her family will never again be able to hug her, kiss her, hold her, tell her they love her. She will never get to live the dream of marine biology that she worked with tenacity to achieve.
Seth and Kat (who despite whatever fate they may both achieve) are imprisoned in the hell of their own souls and choices. Their parents and siblings who watched them with love and dignity and tried to guide them through their life course will forever be left to wonder what they did and the guilt they have must be thick and difficult to live with.
Just some Friday musings.
