Albus couldn't quite help the way he blanched just a bit at the idea of another piece of luggage being opened.
There was no reason to assume that whatever he'd let out of his own suitcase would have been exclusive to him. These sorts of things could be locative. At the same time, the only way to know for certain was to test, to try, to replicate results. A quiet, devious little voice in the back of his mind seemed quite certain that surely he could endure an encore, for the sake of knowing one way or the other. What was the worst that could happen? His own suitcase hadn't actually done him physical harm. While he might not have particularly wanted to reduce himself to a heartbroken mess on the floor, surely ignorance was too high a price for his pride.
"That's not an errand I'd pursue with haste," Albus was obligated to say, pressing a hand against his own chest, as if it might ease the lurch that followed each beat of his heart. "Unless, of course, I had good cause." The last of his words lilted with a bit of inquiry, wondering if Draco knew what sort of thing he might be able to expect upon opening the piece of luggage in his grasp.
