He wouldn't be that offended if she did touch it, but he appreciates her restraint.

Otherwise, it looks like it's all a big mystery. She seems like she's really trying, though, so he assumes that's the best that can be done for the moment. He apologizes for her having to deal with all of this craziness, and thanks her for her help. This is the warmest welcome he's ever gotten from an alien society!

At that point, he'll let her get back to her business. There's a lot of people to deal with.
