Mandy felt internal panic when she heard other voices form behind them and then spun around to see Draco, Crabbe and Goyle as she moved to a sitting position. She caught Harrys arm out of that internal instinct because she knew it could turn into a fight in a matter of seconds. Then she shook her head, like she'd be able to stop it. She sighed and ran a hand through her hair. "Nice to see you too, Draco." she said pleasantly, still gripping Harrys arm.
