[Robin grins sheepishly.] It's possible that I was distracted when such things were being explained to me. I thank you, my friend, and shall take no more of your time - only leave me with your name, if you will?

[The astute observer would be able to intuit that by 'distraction', what Robin likely means is 'trying not to keep my brain from exploding at the idea that I am suddenly 2000 years in the future'. Whether there is more to it is, of course, unclear without further discourse. It may or may not be equally observable that Robin is still rather shellshocked about the whole thing and covering as best he can.]
