"He's a future," Andrew tells Lizzie of David, "and so far I've only dated the past." He's determined to win David, and in order to do that, he wants to transform himself into "someone David can love." This sounds like a touching sentiment, until you remember that it's coming from Andrew Cunanan.
Jeff draws the line at pretending to still be a naval officer, and later in the episode, he and Andrew come to blows over that postcard we heard about in Episode 4, with Jeff openly accusing Andrew of trying to out him.
Andrew's lies are beginning to catch up with him and clash with each other, and the party sequence culminates with a photograph that really sums up this messy collision of Andrew's two worlds.
On one side of Andrew, Norman and Lee Miglin; on the other, David and Jeff, who have only just met but have already struck up a warm, easy rapport that's infuriating Andrew.
Thanks to the show’s reverse chronology, the history of these relationships is deliberately ambiguous, and so it hasn’t been clear up until now whether Andrew’s obsession with David is fully delusional, or whether it sprung from something real.
