Cheno's costume last night

"I don't really get the ending,all i can go with is when after several months,Judith saw Pat sang,and later she kissed him on the toilet,after that the story back to where Pat went down from the stage after he'd sung,and he went to the italian lady.I just don't get it,what Judith exatcly meant when he kissed Pat that she had seen,and did Pat end up together with The Italian Lady?Please help me,thank u very much!" Quote from someone on IMDB in reference to a movie he/she didn't understand. Such grammar!
