Collaring Outside the Lines

Collaring Outside the Lines is a radiant side quest in the Fallout 4 add-on Nuka-World.

Detailed walkthrough
After you receive the quest, you'll be given a target to collar. This target may be in a city or settlement, which will turn hostile if you collar your target in broad daylight. You have the option, with a minor speech check, to ask the target to follow you. Lead them away from people to avoid having to kill anyone. Speak to them again and the best choice is an easy speech check telling them you have a necklace they would look good in and collaring them. Return to Mason for a reward.
