When Isla thought about it again, it was a bit contradictive for Magnus to ask Sebastian to punish the pedophile dark mage while asking him to not hurt himself. But there was a difference in punishment and revenge.
Magnus might've known what Sebastian was potentially capable of, but he didn't know that he had been suffering from torture himself, and handing over the pervert to him was a gamble for Sebastian's sanity.
Still, Magnus believed in Sebastian.
He believed that a young man as strong as him, who might've spent his whole life training to be this strong, would be able to endure his own heart.
And this time, he was right.
Sebastian, contrary to Loneborn's belief... was even calmer than ever. After knowing that he had Magnus on his side, who bore the weight of hatred and judgment towards the wrong, Sebastian walked into that cell with emptiness in his eyes.
"Who are you, boy?"
