The Doctor scoffs at that. "I like this outfit very much. I look like the cool professor. Bow ties are cool!" He shook his head and pointed a finger at Narvin. "At least I don't look like I'm wearing the robes of some secret society." The Doctor raised his hand, pointing at Narvin. "There is always time for politeness."
The Doctor stared at Narvin. "Just when did you come from?" He knows that he can't tell Narvin what he knows about the future. Spoilers and all that. Still, he'd help in any way that he could. Even if it was for him. “Don’t you ever question my concern for Gallifrey. Gallifrey was my home! I did everything I could for Gallifrey. I was protecting our world.”
The Doctor glared at Narvin. “My TARDIS is down by the docks. Come along,” he grumbled. He motioned for Narvin to follow him down the plass to his TARDIS. "There is always room and time for manners."
