Ezra and Sabine are walking back to the Ghost where they're crew waits for them, after a mission. They make small talk as they go. Talking about art or just random dumb sh!t they've done. They start to pass a cave when Sabine felt the ground shake a bit. She stopped but Ezra kept walking. Sabine looked up and saw dust start to fall. She had just split seconds to save herself and him.

Sabine: "LOOK OUT!" Sabine grabbed Ezra's arm and pulled him into the cave, right as the large rocks and a bolder fell on the exit shutting it off from the outside.

They fell down a slope and stopped at the end of it. Sabine was knocked unconscious by the fall
