Lisa and Ethan move to New York, reconnect with old college friends and learn that some secrets are harder to keep than others.

Facing a brutal deadline, Ethan brainstorms ideas for his Y.A. novel. Meanwhile, Sam, Lisa and Marianne meet some admirers out on the town.

Tensions flare, suspicions grow and mics drop at a lavish wedding reception, where Ethan takes his new persona out for a spin.

Lisa makes a big decision, Ethan and Sam reminisce about old times, Nick plays a prank, and Max makes an awkward confession.

The gang gets together to celebrate Sam's 40th birthday, where Lisa suffers a crisis of conscience and Nick's announcement catches everyone off guard.

The gang is forced to put on their happy faces and reconnect at Max's swanky engagement party, where "severe awkwardness" is everybody's plus-one.

Sam tries to halt Jon's shaming campaign. Ethan and Lisa take a stroll down nostalgia lane. Nick makes an effort to act his age.

The gang attends an extreme funeral, Ethan gets an earful from Felix, and the awkward encounters keep on coming for Lisa.

Max and Felix's big day arrives -- and so does the drama as secrets are revealed, confessions are made, and poorly timed punches are thrown.
