Bianca comes back and hollers Rickaaaaayyyyyyy, Pat gets a fright and falls over the bar in the living room and knocks herself out, whilst dreaming about Frank in his dickie bow. As she comes to and starts to recover one of her earrings falls out and pierces her heart. She dies. The end.
Pat will come back with Peggy claiming it was all a dream. Afterall there is not much left after advertising bingo. So they will need the money to keep them in wigs and earrings. Mind you the scene ages ago when they were in the ice cream van pissed was quite funny.
