The Unusual Custom The Need to Watch Rocky asks to watch Grace sleep. Grace finds it creepy but learns that it is a cultural imperative for Eridians. They evolved to protect each other during vulnerable sleep states. The Explanation Rocky explains that an Eridian cannot wake up on their own during sleep; they are paralyzed. They rely on others to watch for danger. This is a deep-seated instinct. The Acceptance Grace accepts the need. He sets up a bed in the tunnel so Rocky can watch him. This becomes a nightly ritual.
