What Remains

Liam arrives at the compound perimeter in the early evening. He doesn't come through the gate. He stands in the dark outside the walls just like the ones he grew up inside. Same concrete, different wreckage. After a while, Elias comes out. They face each other without speaking - two people who understand everything about each other and ended up in completely different places because of it. Elias says: "You can't stay." Liam says: "I know." Elias says: "Don't disappear." Liam nods and goes back to the van, and sits with Lilith in the dark. He takes her hand and tells her he's going to find someone who can help her. Tells her he doesn't know what he is yet, but he knows what he isn't anymore. He starts the engine, and drives away. Post-credits: a small room in London. Liam's wall map - but the nuclear facilities list is gone. Pinned to the centre in its place, a photograph. Four children on a park bench in South London. Maya is laughing. Liam is looking at her with a long-gone smile.
