Sebastian took July's hand when she was about to enter the library, he turned her around to make her face him because he was not yet done talking to her, but she kept pushing him away.
He wanted her to talk to him. He didn't want her to treat him this way.
"We are done, Seb," July said sternly. "This is not even up for discussion. I will choose him and I will always choose him over and over again."
"Even if you can't have a child with him?" Sebastian asked her, this was the main problem in the relationship between July and Knox.
July only wanted a simple little family, a child from the man that she loved, but Knox didn't think that way. He was Chaos's shattered soul. He shouldn't have a child, because there was a high chance his child would end up the same way as him.
