Glee Season 5 wraps up on Tuesday, May 13 and will be off the air until it returns in September 2014 for its final season.

In Episode 20 The Untitled Rachel Berry Project, Lea Michele receives a surprise opportunity of a lifetime when a famous TV writer, played by Kristen Schaal, offers her a TV debut.

Meanwhile, Mercedes and Sam must make a relationship decision as they take separate career paths.

Mary Halloran (Schaal), a famous scriptwriter in New York becomes interested in Rachel Berry's life and she is offered a rare opportunity to be featured on TV.  But Rachel and the gang seem dismayed with the visitor's quirkiness and inability to capture the very essence of Berry's becoming.

The lead female star encourages some rewrites to the story but Halloran will find it hard to reconcile her eccentric ideas with the rest of the group.

On the other hand, Mercedes is on her way to promote her new CD and will be soon launching some mall tours.

Sam is on a different path - taking on a few modeling stints and might appear naked on a city bus. The two have to make decisions to follow their lifelong dreams or break the tide for the relationship to survive. Will they endure? Will they survive?

Blaine's career is rising earlier than expected. He will soon start something he hasn't even dreamed of, but it will require him to reveal a secret that can either make or break his relationship.

In another scene, Blaine is caught in bed with Brittany. Even Gleeks would blow their minds trying to figure out how and why!
