ALIE might still be alive?
At the end of season three, Clarke pulled the plug on The City of Light, effective killing ALIE1… or so it seemed. ALIE did upload her consciousness to the part of the Ark still orbiting and, in the trailer for season four, we see something pursuing Miller, Raven, and the others through the woods. It has a Terminator-like target screen and, as Raven dodges the bullets, she seems to look up to the sky. Are ALIE’s drones still chasing the Arkadia clan? And, if so, does this mean ALIE is still alive?
The radiation is the biggest immediate threat.
“We have to focus on the radiation,” Raven tells Bellamy, among others, “finding someplace safe.” Though this seems like a relatively cut-and-dry plan, it’s less easy in execution. In the next sequence, we see Bellamy, Miller, and Monty fighting against some of the Grounders. Can’t we all just get along guys?
