The stranger has watched the curious movements of the little girl, and the gentleman who interrupted her approach. Snatches of their conversation reach him, and he is concerned, as it is not his intention to frighten her. Or anyone.
He merely wishes to be left to his thoughts.
This world is so different, this future-place. Shock still reverberates through him, that this is not a dream--he is hundreds of years away from his home. He cannot fathom it, simply cannot fathom how.
He is not frightened, though. He looks at the pen in his hand. Too many marvelous things to discover.
He pushes his hood back, as it is clear the man now approaching has no intention of anything but interrupting his solace.
