Draco narrowed his eyes on him, not because he was glaring but because it was increasingly difficult to focus on Percy or, well, anything really the way things kept spinning and turning. His face was flushed obviously given how pale he was. "Is it noticeable very much?" He asked although he wasn't sure how it came out because his tongue was moving much slower than his brain. "It's for the vampires, to keep the vampires away, even thought it's moon..." He paused. "Moon..." He couldn't quite finish his sentence or grasp on to a thought long enough to finish it.
"It was a bad idea, I've never been--I can't stop it. How do you get undrunk?" He was going to assume Percy was familiar with alcohol, he had a depressing, horrible life. He probably drank it all the time. He reached out a hand for him, his fingers swiping at air.
