When the Doctor and 'Rose' first stepped into the offices in Canary Warf, they were met with a surprising sight. There were two men arguing very loudly. The first man was wearing an oddly familiar WWII coat, and the second was wearing a nice, grey business suit. The first man, clearly not noticing the Doctor or Jackie, started yelling.
"What do you mean I'm NOT allowed to see him," he yelled at the second man.
The second man, trying to calm him down, answered, "I'm sorry but you do not have the authority to see him."
The first man was clearly getting very frustrated at the second man. The first man then said, "What do you mean I don't have the authority?!" He was practically yelling. "I'm Captain Jack Harkness! I should have the authority to see anyone I want!"
At that the Doctor finally realizes who he was. The Doctor then walked up to Jack and taped him on the shoulder. "Um … Excuse me Captain Jack-" but he was cut off by Jack.
"Leave me alone. I don't have the time to talk to anyone right now!" Jack almost yelled at the Doctor. He then turned around and said a bit more calmly, "who are you anyway?" He looked about ready to punch the Doctor.
"You never do change do you Jack" The Doctor says stifling a laugh. Jack's expression changed to confusion.
"What do mean? I never forget a face, and I know I have never met you before!"
