Frank Bryce overhears Voldemort discussing plans with Wormtail. “You will have your reward Wormtail,” Voldemort says.
“I will allow you to perform an essential task for me, one that many of my followers would give their right hands to perform …” Wormtail does not understand that Voldemort meant it literally when Wormtail had to give his right hand to bring Voldemort back to life.
