Parallels between Clarke and Madi/Thelonious and Ethan[]
" She's a Nightblood named Madi, and she's been with her ( Clarke ) for five years. They are, for all intents and purposes, bonded the way a mother and daughter would be. So Clarke loves her, and her decision making process has chanced, just as it does for anyone who has a child. We'll tell the story of how they've been surviving as the only two people on the planet - until that ship shows up"
Madi is a pre-teen girl that Clarke raised for five long years. Clarke's foster daughter. When Clarke lost 'her people' and her leadership when she as left alone on Earth, she found Madi. If she has been living with Clarke for five years, Madi was five or six years old when Clarke found her.
But Clarke is not the only character that will have a pre-teen as a foster child. Thelonious Jaha picked Ethan Hardy after Hardy's father was left outside of the Bunker during the Culling 2.0. Thelonious as Clarke lost his leadership after Octavia appeared as the new Commander/Leader of the Wonkru. Madi gave Clarke a reason to live. And Ethan with Thelonious? A similar process could have happened with the former Chanceller. However, the biggest difference between Clarke and Thelonious is that the blonde was alone for a year...with no people to lead because simply there was no one to lead. However, Thelonious has been living with 1199 people for 6 years.
