Note

 * Causeless Rebel shares the same Vault Boy image as Slayer.
 * The name is likely an allusion to the film Rebel Without a Cause.
 * This perk is currently not granted despite the game message telling you it is - see talk section.
 * This perk seems to not show up in your PipBoy after receiving notification you've acquired it.
