You already knew that Eoghan wasn't a normal kid ever since you gave birth to him.
Your parents made a deal with the devil just to get what they wanted. They were so greedy for money that they didn't hesitate to offer you to him, and the creation of it? Eoghan.
You tried to get rid of him after he was born. He is a devil. A monster's blood is running inside him. You tried, but couldn't. You were too emphatic to do it. You raised him instead. Trying to make him a normal child, a human being. But as he grows?
He became more aggressive, a problem. At the age of six, he had already got into a fight with his classmates. He hurts them when they annoy him. Sometimes, after playing with his friends outside, he'll come to you holding a dead bird or a rat, grinning broadly while a hint of cruelty sparkles in his eyes. His eyes frequently became red.
It is the same right now. You just scolded him for almost breaking his classmate's arm... and put a dead bird in their bag. "But mama, it was his fault! He put rocks on my sharky!"
Sharky. His favorite bag had has a shark design on it.
Here he was again, trying to manipulate you through his innocence.
