Okay, so that was a major fail. Why were Gryffindors usually such crappy liars, unless they were brilliant chess players? It dawned on her when she saw Atticus's face that it made absolutely no sense for her to be joining her father on an emergency and then to be going the opposite direction away from the emergency room.
As she saw it, she had two reasonable choices. Find someone to headslap her for stupidity. Or--take him into her confidence, at least in a limited way. If her father was hurt enough that he wasn't going to be able to deal with it at home, she knew she might well need help if her own magic didn't work. How or how badly he was hurt, well, she just didn't know.
"Alright," she said quietly. "Come with me. But not a word to anyone. I don't even have words to tell you how important secrecy is until further notice." She motioned to him and headed up to her father's office.
She found the door was locked. She tried to use her magic, and it simply sputtered.
"Daddy," she knocked and called quietly. "Its me. Open the door." There was a pause, and then the door opened on its own.
The only light on in the room was the desk lamp, making the room look very dim. But she clearly saw her father laying on the floor in front of his floo, sitting up, leaning on the hearth. His left leg was a mass of blood, bleeding profusely. No wonder he'd come here.
She hurried to him.
"Where's Brian?" he asked.
"Home. I didn't know I needed to bring him," she said. "And it wasn't over when I left."
"Damn," he sighed, wincing sharply. "At the rate you're going, you're liable to turn my leg into a lamp. 'Evening, Atticus."
