Riley Sticks Around
Riley after surviving his paranoid brother Kyle normally goes to where all good NPCs that disappear go to Vault Heaven. Instead of letting him live out the afterlife with him and his reunited brother, let him continue his miserable existence without a brother in Diamond City. Riley will remain in Diamond City acting like other generic Diamond City Residents.
