Further to my last post. (If you haven't read it yet, go and do so.)

I do, in fact, already have some ideas about Terry; who he is, how he came to be, and why he was hurrying after the Doctor in the first place. But I'm suddenly struck with a powerful curiosity about what other people conjure up when they are given very little information about a character. So, tell me about your Terry.

What does Terry look like? How tall is he, what colour is his hair? How does he wear it?
How old is he?
What style of dress does he favour?
Where does he come from?
What does he do of an evening?
What does he do during the day?

If you like, you can tell me how he met the Doctor and what was chasing them. And for bonus points, tell me which Doctor this is (and which TARDIS).
