“Nevermind” is episode seven of season six of The 100.
At the end of the previous episode, “Memento Mori”, when Josephine went to sleep, Clarke woke up in her cell on the Ark, which is where this one begins. The cell has far more drawings in it, depictions of things Clarke experienced after the Ark, and there’s a constant whispering of many voices. She leaves the cell and enters the place she lived with Madi. Her father is there. She asks how this is possible, how he is there. He asks Clarke what’s the last thing she remembers. She died. Clarke thinks she’s dead, and gets upset. A storm comes and her father asks her what she can hear, beneath the rain. A heartbeat. She’s still alive. Her father or, rather, her image of him, tells Clarke there are no answers here for her. She has to go figure things out.
She leaves the building and returns to her cell. A.L.I.E. is there. Clarke says she destroyed A.L.I.E. Yes, and A.L.I.E. saved her. A.L.I.E. is why Clarke is still here. A.L.I.E. may be gone but the repository of her memories is here because of A.L.I.E. You’re welcome. The neural net interfered with the drug used to wipe Clarke’s mind. Clarke exists because of A.L.I.E. But she won’t if the Primes figure out how Raven was freed. A.L.I.E. removes the memory of that from the wall. She advises Clarke to keep it safe. A.L.I.E. says Clarke’s painful memories are hidden deep in her mind where she won’t have to face them. Clarke remembers she saw a door that wasn’t hers. She goes and opens it and Josephine comes out. Josie says Clarke shouldn’t have opened that door; Clarke’s body isn’t big enough for the two of them. Clarke’s body is asleep and dreaming.
Josephine says this is a mindspace; it keeps minds separate so the body doesn’t die. Opening the door advanced brain deterioration. She’s been through this before. Before Gabriel perfected the mindwipe, Josie awoke in bodies that still had their previous owner active. Leads to brain haemorrhage, stroke, death. Not very pleasant. Josie wants to know how Clarke is still alive. Clarke isn’t going to tell her. She suggests Josie find another body. Josie could, but she doesn’t want to be kept on ice. And she likes Clarke’s body. If Clarke tells Josie how she survived, Josie will ensure her people live happily. Otherwise, they both die, only Josie will be reborn in another body and Clarke’s people will be kicked out.
The mind is where Clarke keeps her memories. Try not to think about them. Which naturally leads Josie to the cell full of memories. Josie says she can always figure people out. Clarke may think she’s badass, but she has self-doubt. Josie would bet Clark has the memory on her. They fight and Josie is killed. Only death isn’t fatal for her; the mind drive backs up her consciousness. Josie can’t die in the mindspace. But she bets Clarke can. They can do this the easy way or the hard way.
Clarke picks the hard way. She runs into Octavia, as Bloodreina, who questions decisions Clarke made. And asks Clarke shy she’s arguing, because Octavia is just a subconscious projection of Clarke. Clarke runs again, and encounters the body of Maya, who died in “Blood Must Have Blood: Part 2”. A.L.I.E. said Clarke kept her bad memories buried. Looks like she’s going to encounter a few, and the dead don’t remain dead in Clarke’s mind.
Josie is confident she’s going to win eventually. She has over two centuries of experience, including experience at manipulating people, and has her mind drive keeping her alive. However, even though Clarke has self-doubt, guilt and much less experience, she does have one thing going for her. Over and over again, she’s proved she is really, really hard to kill.
