"Stop being an idiot! Of course I care! I've always cared about you, but you're just like Rose! You lot always expect me to say it and make commitments and be with with you! It doesn't work like that for me, Jack! Maybe if you stopped to think about the things I do, then maybe you'd realize it!"

He was gone, now. He threw another punch towards Jack's face, and another. He knew he should feel shame for how he was reacting and how he was hurting Jack, but there was nothing but anger.
