4 Major Things to Remember Before The 100's Season 4 Premiere

If there's one thing to be learned from this show, it's that whenever something kind of good happens, something really bad is probably not far behind. When Clarke finally reaches A.L.I.E.'s kill switch in the City of Light, the artificial intelligence tries to convince Clarke not to shut her down and take away the chance for everyone to live without pain. Why? Because the remaining nuclear power plants on Earth are melting down, and soon the planet will be a big ball of poison and misery. Forced to choose between two huge evils, Clarke puts her faith in her people. She shuts A.L.I.E. and the City of Light down and banks on the chance that the people on Earth can find a way to survive — instead of letting them continue living as mindless slaves. Hooray! However, this means that nuclear apocalypse is back on the menu, for everyone. Here we go again.
