Why would Lorelei tell RJ that she told PK that RJ and PK shook hands , i mean  Lorelei hates RJ now , because RJ raped and killed her sister,and in the RJ video RJ said "Lorelei told me what she told you about shaking my hand" , because he wants to cover on who ever told him which is Lisbon , because Lisbon is the only one who knows that Lorelei told PK that  RJ and PK shook hands .
