What would happen if one put a Metamorphagus' hair into a Polyjuice Potion? Would you be able to morph? Or would you take on the form that that he/she was in when the hair was taken? Someone in a story I'm getting ready to write takes a Polyjuice Potion to become Tonks, so that's why I need to know. It's not going to be a major plot point, so that's why I'm asking. Thanks in advance!
