The Perfect Target

At first, Jayden planned to utilize any one of the servants as long as she knew they were easily manipulatable in order to use them to infiltrate the mansion, only planning to knock them out since she saw no real use for killing them other than a small amount of "XP", as Moby had previously put it.

However, after she witnessed what Preston was doing, she threw that idea completely out the window, opting to both disguise herself as him and kill him for being an infestation on the face of the earth, the extra XP was only a bonus.
