Two minds touch. Two beings converse. One is of this world, one is not. The Terran is intrigued. He has never encountered a Time Lord before.

The Doctor is alien, but there is much about him that is familiar. He is intensely curious about everything. He explores wherever he pleases. He greets everyone while remaining aloof.

He can be cruel - not by intent but by nature. He takes what he needs without hesitation or apology. He radiates superiority.

He is like me. Though the Doctor has undeniable physical flaws, the Terran concludes that he would make a fine cat.
