Some Dogs Bite

Casey:
How can I nick a baby that's my brother?

Venetia:
I ain't shouting. I just got a big mouth. Better get used to it.

Casey:
Oh, I wish I had a best friend.

Venetia:
You don't need one. You've got H.

Casey:
Yeah. Well, we've got the same mum but different dads, so he's half my brother and half an ordinary person.

Casey:
We're not good, but... we ain't bad... are we? We're just... not anything special.
