Hawke was no dinosaur handler like Owen but he understood mabari and their body language. He couldn't stop thinking of her like a big dragon-y mabari even though Owen told him not to do that. He was a stubborn idiot but he was aware of it.
"I do wish you could talk," he said with a little smile. "Because my guess is there's something in the woods? Something you can't handle? Or are afraid to handle?"
Because that's what her body langue told him. Well, what it would've told him if she was a mabari. Warden would've simply pushed him or dragged him where he wanted Hawke to go. Considering the side of Blue's teeth and their sharpness he appreciated her not using them. He almost reached out and patted her on the head but stopped himself.
