Hugh felt every shred memory that Aric had lived throughout his life. He witnesses the tortures, the pain, and the anger.
Aric never wanted to destroy the school, he was just forced to do it. Even then, he was still hesitating with every second that passed.
As soon as Aric saw Hugh inside this room, a plan took shape inside of his mind. Hugh wanted to stop Aric, and Aric let him do that.
Aric knew that his body would not let him lose a fight with Hugh, so he forced Hugh to transform. He wanted to lose. He wanted to be stopped, even at the price of his own life.
At the very end, Aric did not feel pain, but relief. He knew that in death, he would get the peace that he always wanted. He would no longer be controlled by his own father.
Hugh could not help but shed a tear as he remembered all of Aric's memories. Aric was never an enemy, but a misunderstood friend. Now, his blood was tainted with the guilt that he would carry throughout his life.
