I would have punched Thorin in the face or come back with a nasty burn if he called me worthless. TAKE THAT THORIN!

"You're worthless,"

"Wow, if you're callin' me worthless, you must be so far down you can't even see me!"

Or

"You're looking in a mirror."

Just a question, but what would you say to Thorin if he called you worthless?
