- "While speaking with inhabitants of the Ninth World, you will sometimes hear their thoughts. This is often helpful, though rarely appreciated."
Scan Thoughts is an ability unique to nanos.
The surface thoughts of most people or creatures you speak with appear in conversations. This can help glean NPCs' motives and intentions, and sometimes adds new avenues of questioning, but is cryptic enough to not spoil a quest or make the game easier in any way.
