A last of the Time Lord might not have aura of who they are. The Doctor might put Spike in a small category because the Doctor could rate very high as dangerous. How many beings you know that destroyed his home planet and fourteen other worlds? So, many things he did so many stories he has.
Heck, Time Lords where protecting themselves specifically from Vampyres because Time Lords had regeneration artifact that had let Time Lords to gain regeneration factors. They even possessed of the power to die and come back in another body as a new reincarnated body. They didn’t need blood or to survive from other life sources. That’s why MOST vampires had wanted to find Gallifrey to take over for their resources. Well, Gallifrey was destroyed in the Time Wars. The Doctor had to stop it and sacrifice his people to stop the endless war. It was a price to stop the war, but, later he realized his Time Lord enemies still lurk in the shadows of time to haunt him of their existence.
Though, many people had noticed that the Doctor wasn’t just a simple traveler a few even knew just by looking at his dark brown eyes. For instance, William Shakespeare knew the Doctor was not from this world. How did William Shakespeare know this? Maybe, the old poet good eye to spot character?
Though, the nice fact about the Doctor’s past is his character and he how he hides and masks it. He won’t simply tell you either, unless he has to make a threat. But, he had seen a lot, he had died nine times, he saw the beginning and the end of the Universe, other dimensions, saw beginning of human creation to the near end of the human race.
When Erika had mentioned ‘good blood’ the Doctor had missed that metaphor saying. He took as blood as blood brothers, or blood as lineage. Being over nine hundred years old, living a few different regenerations your mind gets filled up with many things.
The Doctor had cocky grin just to match Erika’s mood. He liked to play the game as I got the girl’s interest and you lost her, game. Though, he was interested of Erika and everyone else. That’s why he liked this mansion. It’s a play ground of knowledge knowing people. Everything was constant changing. He didn’t mind that. But, he really didn’t like to be stuck in a spot and people being held against their own will.
The other honorable thing about the Doctor, he feels he had to be the knight of fixing things in time and universe. Well, that’s what his REAL title states for. The Doctor of fixing everything and his enemy the Master was the Master over all things. But, the Doctor had lost his arch enemy. He had died in his arms. The Master had chosen to accept death to get the Doctor at the end. Meaning leaving the Doctor with guilt, pain, and being the last of his kind.
The Doctor stuck out his lower lip and nodded, “I reckon, punching a fountain. It’s not the fountain’s fault. What did the fountain deserve to be punched?” The Doctor of course was throwing nonsense out so they might not truly know him.
“How would you like to be a non-animated object and be punched because someone was mad?” He winked at Erika. He was having fun playing a little. Or was he being rude? He wasn’t sure.
