Almost fifteen years ago, Duke stepped into the capital for the first time. He was not even supposed to meet with his older brother, but that was his own mission. Duke didn't have a driver's license yet; neither was there a Locket to ferry him around. However, he still ventured to the capital.
The current head of the Bradshaw family, William Bradshaw, was deemed responsible for that incident that killed Dominique and Arryn's father. He was even caught saying how it was brought by him. Those words sealed his fate, and Duke watched the gullible man crash his car into the building and shoot William Bradshaw dead that day.
"Doesn't that mean… I killed the wrong person?" Duke murmured as he let the fact sink in. His planning might be as flawless as it was before, but Pareidolia's network was nothing close to its state right now. There would be lapses, and Duke understood that it was out of his hands at this point.
