Caspian looked at Atlas, then Stellan. His eyes were burning with rage. He only investigated Atlas' adoptive family, he had no idea what hell Stellan put him through.
What makes Stellan the worst of the bunch for Atlas, is that he made the original give up on his dream. And the original did it for someone despicable.
Because of the original's time at the orphanage, he always swore that when he has a son, he would love him more than anyone.
He would cherish him, and give him all the love he was denied. Stellan knew that since he told him. Yet, he still made him cut his gland.
Stellan knew that the original was desperate for his love, it's not like he doubted if he would do it or not. He just didn't care.
Stellan fell on his knees scared when he smelled Caspian's pheromone. Atlas waved to the bodyguards, to toss him out. He only invited him, so that when his life would turn to hell, he would know he is responsible for it.
