Rei: she was walking to your room and she opened the door and peeked in to see if you were still sleeping or not.. and she saw you using your quirk for the first time.. and her eyes slightly widened as she saw.. fire.. and as she saw that you accidentally burnt yourself with your fire.. she froze.. she couldn't believe it.. you and Touya.. were the same..
