Lucius's arm slides around Bella's waist as she leans in, and he seems to be watching Draco choose alcohol with a rather avid gaze, his eyes just a bit unfocused from the alcohol and drugs already consumed. Murder is, however, the very best stimulant - a lesson Bella taught herself once he was away from Hogwarts and then Durmstrang. The prospect of it - the prospect of a Muggle's blood soaking into a ground - is better than coffee for pulling him out of the haze, at least a little bit. It's funny, he thinks. He's not heard that supervision is much of a feature of British Muggle life. If it was, their extracurricular activities would be harder. Wouldn't they?

If he were a little less drunk, he might try to puzzle that idle thought out. It's easier to just let his lips curve in a lazy smile as they turn back up the aisle. He's got Bella to keep upright as it is. "It's a dangerous world, I suppose," he drawls. It really is just like Draco's from earlier. "Who knows what creatures may stalk the night." One finger twines idly around one of Bella's glossy curls and his smile widens just slightly.
