The 100 Anaconda press release”
THE PAST – Clarke (Eliza Taylor) confronts a new adversary. A surprising connection takes us back to the past and the nuclear apocalypse that destroyed the Earth. Bob Morley, Marie Avgeropoulos, Lindsey Morgan, Richard Harmon, Tasya Teles, Shannon Kook, JR Bourne, Shelby Flannery and Chuku Modu also star. Ed Fraiman directed the episode written by Jason Rothenberg (#713). Original airdate 7/8/2020.
The theory is that Clarke may bargain with someone on Bardo to get them to release her people or she met Bill Cadogan in a flashback. What they will talk about, maybe about the earth and the different survival techniques (bunkers, planets, etc.) that they used.
The Bardo theory also feasible; if it is one thing about Clarke that she is known for, it trying to come to an agreement for everyone’s lives. However, those negotiations always ended in a morally compromised absolution.
I guess you cannot make a peace offering with the ‘bad guys.’
And we finally get to see how the world ended. For the first time.
