I’m Bill. I used to work at a university canteen, until I met the Doctor. He was a lecturer there, but he’s actually an alien who travels in time and space. He took me with him on his TARDIS, and we’ve been having amazing adventures ever since. We’ve seen aliens, robots, monsters, and more. It’s scary, but also exciting. And the Doctor is brilliant. He’s funny, clever, kind, and brave. He’s taught me so much about the universe and myself. He’s my best friend. And I’m his companion.
