'Go to the desk on the far left and state that you have a goblin item you wish to return.'
"Let's see it then," the odd creature demanded rudely. "Give it to me."
Ignoring the guards standing to either side of the teller and with a wide grin, Mercy drew the dagger and pinned the teller's hand to the desk. Her smile deepened as she placed her hand on the pommel and pushed it down.
Neither guard made a move, though she did note that each seemed to be doing its best to hold their mirth.
"Do you still want it?" she purred. A frown appeared on her face when there was no response. "Do we still need the statue that brought us here?"
'You do not.'
"Is it worth anything?"
'It is not.'
"Harry?" she turned back to the boy with a smile. "Would you mind giving me the statue? If you don't want it for anything, I mean," she added a touch shyly.
"Sure," he agreed.
"Thank you, Harry." In one smooth motion, she whipped around and delivered a shattering blow to the teller's side. "I'm talking to you! Do you still want the stupid knife or would you rather I take it back?"
"Take it?" the teller wheezed.
"You'll recognize that it belongs to me and my blood?" she asked, punctuating her question with a twist of the blade.
"Yes!"
"Wonderful. We have only two more bits of business before we go," Mercy said with a smile. "The first is this key." She nodded for Harry to drop it on the table. "We would like to declare it and its contents to be ours by right of conquest. Unless you would like to object and try to take it for yourself."
"It's yours!" the teller squealed. The right guard lost its battle and began laughing openly, the left soon followed.
