Try to pass as a muggleborn witch

"Yes, thank you for the help."

Harry offer him a nice smile and follow him.

What Harry could not see, following the goblin was his nasty smile. He just found a hot naive witch to trick into slavery for the goblin nation. All he needed to do was making her sign a few paper and she would be force into slavery. With the return of Voldemort it was time for the goblin to retreat underground, but not without a few toys to make the time pass more sweetly.
