If it were up to me, we would have just let the both you in, but the mayor's calling the shots. And, well, you saw how mad he is,

Danny Sullivan is the gatekeeper for the main entrance of Diamond City in the Commonwealth in 2287.


Danny is the Diamond City security officer responsible for monitoring the main entrance to the city for potential threats and troublemakers.

An incident surrounding a recently-published controversial news story, "The Synthetic Truth," left Publick Occurrences reporter Piper Wright banned from Diamond City. Under the orders of Mayor McDonough, Danny is reluctantly denying Piper access to the city.

However, Piper uses the arrival of the Sole Survivor to pressure Danny into opening the gate, by convincing him that the Survivor is a local trader coming up from Quincy and threatening him with the wrath of Myrna if the gate is not opened. This inadvertently restores Piper's access to the city.

This character is involved in quests.


  • Jewel of the Commonwealth: Danny Sullivan stands in the way of entrance into Diamond City, after shutting the gate to keep Piper out (on the mayor's orders). The Sole Survivor must join in on Piper's lie to gain entry to the city.
  • In Sheep's Clothing: Danny is found gravely injured after being shot by Mayor McDonough when learning the truth about his identity. The Sole Survivor has the option to heal him before dealing with the mayor.



  • After letting the Sole Survivor and Piper in the city, Danny can be spoken to behind the counter at the entrance. There is an easy Charisma challenge and if choosing to lie to him, one will get the same conversation again and be able to attempt both challenges.
  • If one has not talked to Irma or McDonough yet, the player can ask Sullivan for help, where he will point them to Nick Valentine's office.


Danny Sullivan appears only in Fallout 4.
