Katie has been lonely in her work; she was overworked and didn’t want to go home to her empty apartment. Instead, she went to a bar, where she ran into Julien. Although they’d known each other for 11 years, Katie and Julien didn’t know a lot about one another. Miranda had always been their glue, but Miranda wasn’t with Julien that night. That night at the bar, Julien confided to Katie that things weren’t perfect between him and Miranda—and that he’d done something bad. After continuing to drink and talk, Katie and Julien had sex in an alleyway.

Julien follows Miranda and tells her that he’s been stressed by a business deal with Mark that went wrong. Miranda realizes that the “dirty secret” Mark tried to tell her about Julien was Julien’s affair with Katie. Julien tells Miranda that it was all Katie’s fault, that she seduced him. Miranda threatens to send an email to her powerful friends who can expose Julien’s insider trading. She realizes that she doesn’t know Julien at all or what he’s capable of.
