"Sure," he says, and it's the kind of sure which normally means no or I don't want to but okay. In this context, it's more I don't believe you but okay. "Well, before we can get to step one we need to find some of these things so..."

He holsters his gun again and gestures vaguely.

"Why don't we take a walk. I figure rocky places are our best bet, lizards normally like sunning themselves -- and unless they're radically different from the kind we know I figure the same applies here."

So, lizard hunting among the rocks it is!
