On Christmas Day, Mark and Roger are visited by Collins and Angel, now in full drag, bearing gifts ("Today 4 U"). They invite Mark and Roger to attend Life Support, an AIDS support group. Roger turns them down, while Mark goes to fix Maureen's sound equipment. He runs into Joanne, Maureen's new girlfriend, who bonds with him as they discuss Maureen's promiscuity ("Tango: Maureen"). Mark arrives at the Life Support meeting ("Life Support"). He films the meeting for the documentary that he's making about people living with HIV/AIDS.
