Miles was still processing what Rodolphus was saying about Daphne. All he could think of was the apparent vow where they could not harm each other. Perhaps there had been some good amongst all the nonsense that Dolohov cooked up for them.
He glared at the oily man, still only raising an eyebrow at the idea of protection, glad at least for the moment he wasn't considered expendable. That was good news. Perhaps it was better not to know too much, but then again, not asking questions had put him in a mess before. "So this... has something to do with the spell at the ball?" He felt fearful for just a moment. "What exactly do I need protection for?" Perhaps it would be wiser if Daphne didn't come to the ball - if this was going to be what he had in mind.
He didn't like the look of the vial, or the man, but he hoped to hell this was going to be worth it. Merlin, he hoped there wasn't going to be a needle - he hated those. He turned pale and looked away.
