She deserved better?
Root started off as an antagonist and became what was basically the centrepiece for the show’s 100th episode. Her wish to free The Machine came true, not by force, but by gaining the love and trust from the man she truly admired. Her flirty banter with the hot ISA agent developed into a fully fleshed out relationship where the hired assassin actually became someone’s safe place. Meanwhile, her prediction that she will one day “transcend this reality” came true when she became the voice of God herself.
You think Root deserved better? I dare you to find any other character that has been treated with as much respect as she has.
