Malfoy growled in annoyance as he pushed the small of Hermione's back forwards. Seconds later, a gigantic, Venus fly trap snapped savagely at the spot where she had been standing. He had reacted too quickly for his brain to process what he had done. She opened her mouth in shock and fixed Malfoy with wide, slightly calculating eyes.
"Thanks," she said unsurely, dropping her snare root. His jaw stiffened.
"Gryffindors just have no sense of danger," he replied rudely as he strolled away down the greenhouse. Hermione stood still, pondering whether Draco Malfoy was as cold hearted as he portrayed himself to be. Because, despite everything, people with no hearts didn't save people's lives, not even for a second.
