Panel 1: As she promised in the Saturday strip, Liz phones Anthony back. She apologizes for Warren's answering the phone and states that he's gone now.
Panel 2: She goes on to explain what he was doing at her apartment and why he had to leave: it was too late at night to deal with his shit.
Panel 3: Her voice possibly getting more desperate-sounding, she reassures Anthony that Flyboy is part of her past, Anthony says that he belives her.
Panel 4: He then goes on to say that it's way late and they can talk about things after work tomorrow.
Panel 5: Since Liz did not see his face when he said he believed her, she does not believe he believes her.
ETA: Even if he were to spend the rest of the week saying he believes her, she will not believe him as she wants what I call "Hot martyrdom action".
ETA: As per the next post, prepare youselves for anvils and cinnabuns falling from the skies! The Settleproposal is Friday! Say it with me: [BOXCAR!!!!!]
