I tell him which one then hang up the phone. I tell Sai, "I have a day of fun planned for us. I hope you don't mind but I invited your brother since he seems to know you very well."
I laugh. "Not really. I've only had to take care of myself since I was 13. When my parents died, I had no one else. I did have a bit of money so I did the only thing I thought of. I lied about my age and got my own place. Just before this experiment, I graduated high school. I just... don't know what to do anymore."
(Some much needed character development for Sage.)
