William is one of my favourite characters in this series
Every time he shows up, he brings a regal presence to him. Even in front of Hadrian's abilities, he stands as a giant. He cares so much for his duty and truly exemplifies the title of Servant of the Servants. The way he apologized to Hadrian in Ashes of Man for sending him to the Lothrians and the demise of the Red Company made my heart melt. I felt as though here was a Palantine who actually cared.
Many people might not like Old Billy 23 because of the way he handled Valka's death. But in hindsight, he was completely justified. He needed Hadrian for the mission of The Quiet, and for political reasons. "I was about to make you my son." By honouring Hadrian, he would have saved him from assassination plots. If Hadrian had accepted this role, he would have been sent to Hapsis and killed The Watchers much faster.
Currently reading Shadows Upon Time....let's see what Hadrian and Billy talk about.
