I want to make a script that will do the following for two specific quests: (Maybe more later on).

At a specific stage in the two quests you find a Kindnapped person. I want those Kidnapped people to wear blindfolds. After you find and talk to them the stage changes and they get freed. Ideally I would want them to use an animation where they are tied up, but I'm not sure how feasible that is to do. I'll settle for Blindfolds for now. How would I make sure the item equips and unequips at specific stages in the quest?
