She set out once again to rekindle what little she had left with Mike by arranging a wedding in the basement of a crack house. Mike agreed and brought Frank Murdock and before the faux ceremony could be finished, Mike attacked her with a machete and left Frank Murdock to finish the job in which he set about to chop her up with a hatchet in a 'Richard Oakes-like' manner shouting "I'm going to cut you into fucking sushi and send it back to your parents". It is unclear if Frank did indeed FedEx her remains back to her Tokyo family.
