Story of the Century

Story of the Century is a side quest in Fallout 4.

Detailed walkthrough
The quest will trigger after arriving to Diamond City for the first time and after finishing speaking with Piper and Mayor McDonough. Piper will suggest you visit her office at Publick Occurrences for an interview. When you are conducting the interview, there are no right or wrong answers. There are four or five questions, depending on your answers:

First, Piper will ask about the time inside Vault 111. Second, she will ask how the Commonwealth compares to the Vault 111. Third, she will ask who the Sole Survivor is looking for (this is skipped if you already told Mayor McDonough). Fourth, Piper asks if the Survivor thinks the Institute is responsible. Finally, Piper will ask the Sole Survivor what they would say to someone who has lost a loved one, but is too scared to look for them.

Piper will become immediately available as a companion following the interview.

Rewards

 * Piper as a companion.
 * Nat will give a copy of the paper with the interview the following in-game day.

Bugs

 * If deciding to put off this quest until after rescuing Valentine, Piper will only give the option to be the Sole Survivor's follower, leaving the quest unable to be continued. To completed the quest at this point, the Sole Survivor will need to ask her to travel with them, then use the command menu to talk to her. This will initiate the interview to complete the quest.
 * At night when going to Piper's office on first visit to Diamond City she may not be in her office. When you exit the fight between two brothers about one being a synth will occur and Piper will be hiding in the bushes next to her office. She will not continue the quest. Fast traveling away seems to fix this.
