History
John gained the skill after clicking on his boxers in his inventory. His mother was the first person he used the skill on, though it didn't reveal her character sheet or inventory; it only revealed information he already knew. After using Observe on a bunch of students during a bus ride to school, the skill reached level 3, unlocking a relationship bar that showed people's opinions of him.
