The Doctor had gone back to examining his box when the strange being named "Bob" appeared. "Oh, hello, and who are you?" He said, not really asking Bob, but mostly pondering the question himself. He walked over to Bob, and inspected him with his screwdriver. "Not human, no definitely not human... not human at all." He stated. "What are you?" He now asked, squinting intently at the stranger. "You're an odd one, and old, very old. I'd say even older than I am."
