He'd never be able to twist enough to keep from being burned. And his companion was actually looking to him for a solution, so he couldn't blow it on something silly.

And then the obvious occurred to him and he grinned. He knelt down, lowering his head until he had a good view across the passage. He nodded. That would work. After glancing up at Robespierre, he got down on his stomach and gestured forward. The recesses for the lasers barred walking, but crawling should easily be possible--as long as you kept your head down, at least.
