Blaise knew enough to take the helmet off but he wasn't sure what do with it. Glancing around, he didn't see anyone so he turned so that his back was to the road and discretely pulled his wand out and shrunk it down to pocket size. Surely he'd been careful enough so as not to attract any attention since it was a very small, specifically directed spell.
"I'll have to take your word on that one," he chuckled as he made a few decent strides to close the gap that had formed between them as he'd handled the helmet. "I prefer not to place myself in situations where too many people I don't know or trust are in charge of what could easily be a precarious situation."
