3 - I Love You/You're Different
Margo, portraying Julie, has just finished singing "Habeas Corpus," and is coming on way too strong for Jason's comfort. She tells him she loves him, but he is convinced that she simply wants him to spend the night.
It's worth explaining a bit of the plot. Supposedly, Jason has written Love's Sick about a former relationship. Margo is the actress hired to portray his ex-fiancée, Julie. So, the first part of Love's Sick portrays Julie in an unfairly harsh light. Later developments turn the tables.
