Malcolm pouted a little. That was a funny joke but still. That was his sister's business tone. He listened to her as she struck her deal. Okay, that sounded reasonable. His grades don't slip... usually. The one class he had a hard time in was potions. He had to actively study to get an E in that class. Usually if he got E's, his mother was happy. If he got an A, that would be it. He could get O's if he really tried. Fourth year potions shouldn't be too hard.
"Yah! That's sounds like a good idea!" he reached to give his sister a hug. Yes, he was 14 but there were times he could act much younger. He just loved his sister and could be affectionate with both of his family members. "And my grades won't slip!" He nodded defiantly.
