Finn: Tell me a secret
William: I’m Batman. Your turn
Finn: Obama is my daddy. You again
William: I’d never heard of Germany before I met you, I didn’t know where it is. And although I have been to Africa before, I am still quite nervous to visit
Finn: It's close to Africa
William: My map says it’s in central Africa. Near Congo. I’ll try to come, but Africa is a long way. 
Finn: On foot, yes. But not when you take advantage of Mario.
William: You’re a funny bunny. 
Finn: How many horses do you have?
William: Around 20. But my favourite one died last year.
Finn: I thought Mario was your fav.
William: I love Mario but his best friend was beautiful. A truly amazing horse. With his own personality. He was a loner, but Mario was his best friend. He ignored all other horses. He died peacefully next to Mario. They were together
