Bronn and Tyrion Lannister in “Unfinished Business”

Bronn

I grow poor protecting you.

Tyrion Lannister

Poor? Under my patronage, you've become a knight, you've served as commander of the City Watch.

Bronn

Briefly.

Tyrion Lannister

I'm sure you've filled your pockets.

Bronn

And now, my pockets are empty. You've given me a taste for the finer things and if you want me to carry on protecting you, you'll have to pay more.

Tyrion Lannister

I thought we were friends.

Bronn

We are but I'm a sellsword. I sell my sword, I don't loan it out to friends as a favor.
