The Eleventh Doctor looked at him. He looked quite shocked. He hadnt expected to run into his first form. He was excited by that idea. But still worried about paradoxes. He still found it hard to believe that he acted old and looked old when he was young.
"What am I doing? What are you doing?" he seemed unsure what to say. 
He wondered if the Daleks knew his younger self was here. The Doctor blinked. "And I'm not young... Not really."
The 11th Doctor knew his younger self wouldn't know he was the Doctor, nor that he was much older. He seemed to be scanning around for Daleks still. He was determined to find out what the Daleks were up to. "But if you must know.. I am trying to scan for Daleks. Need to find out what they are up to."
