“Remember Me” is episode nine of season two of The 100.
At the end of the previous episode, “Spacewalker”, Clarke had killed Finn rather than allowing him to be tortured to death by the Grounders in retaliation for him killing Lincoln’s village in “Human Trials”. Lexa, the Commander of the Grounders decides that this means that there can be an alliance between the Grounders and the Sky People against Mount Weather, but some on both sides don’t agree. Which causes trouble.
Raven is not happy with Clarke killing Finn, which is not exactly a surprise, even though this death was preferable to the one the Grounders had planned for him; Clarke is now seeing Finn haunting her (indeed, she is remembering him), and she learns a lesson from it. Probably the wrong one, even if it’s one advocated by the Commander.
Back inside Mount Weather, the remaining people from the original landing are attempting to communicate with the outside, which is harder than they think.
