She admits to working as an assassin, led by Daud, and she admits to playing a part in the assassination of Jessamine Kaldwin.

On low chaos, Foster reveals her true name, Billie Lurk, respecting Emily or Corvo enough to tell them her past.

The nature of their conversation will change depending on the chaos level: Sokolov tells them that Delilah 'had a talent for imagining the world as a better place'. Should the protagonist speak with Sokolov, they will discuss Delilah's past and her personality.

Sokolov is found painting a portrait of the protagonist, while Meagan is on the deck. Before doing so, they may talk to Anton Sokolov and Meagan Foster. On the Dreadful Wale, the protagonist intends to commandeer the skiff alone in order to reach Dunwall's streets. Only then can you eliminate her and take back the throne. Enter Dunwall Tower and find a way to reunite Delilah Copperspoon's spirit with her body to make her mortal again. You must confront Delilah Copperspoon before she changes all the world with her will. Remember, you cannot knock out any of the guards in this room or alert them for the achievement to unlock.Meet with Meagan Foster and Anton Sokolov to discuss your return to Dunwall.

Switch to the past and you should be able to grab the key off of a cushion to unlock the achievement. Once you've snuck into the dining room (you can do this either from the first floor, or by going upstairs and working your way onto the balcony surrounding the dining room), make sure you're in the present time line, then go over to the table and find a spot where you can crawl under it. For example, switching to the present to move up to the barrier keeping you in the piano room, then switching to the past to find yourself past the locked doors and with the barrier gone. You'll need to master the switching between past/present to get through barriers, etc. This achievement is earned in mission 7 'A Crack in the Slab.' After getting the time turner device (one of a number of Harry Potter-like things that show up in this chapter), you need to head out of the piano room and straight across the lobby to the dining room on the far side.
