Jackie is not covered in blood she just works very hard at her Italian restaurant. She is called the wrapper because she wraps presents during Christmas for charities. Her ear is wrapped because no she was not shot, she just got spaghetti on her ear and was too lazy to wipe it off so she tied bandage like paper towel on her ear. this is supposed to be a play on creepy pasta (get the pasta joke, cuz ya know she works at a Italian restaurant)
