We already know that Glee will go Gaga this spring, while Rachel will give Finn Hell during the show's return episode on April 13.

What else can fans expect from the second half of season one? In two words: Noah Puckerman.

"[Mark Salling] has really taken the character and humanized it in a way that has given it a lot of dimension and made it really fun to write," producer Brad Falchuk said. "Mark has a lot of focused stories in the back nine.

"He'll have plenty of moments because when you have talent like that that looks like that and can sing like that - he has a very easy movie star charm about him and an accessibility - you want to write towards that. Puck fans will get plenty of Puckerman."

Specifically, the producer told Zap2It that Puck will be put on a Rat Pack-like number at some point during the back nine episodes on the way. From there?

"If you haven't fallen in love with him yet, after that one... lord."

Falchuk also said Mercedes will have "a couple suitors," while Brittany and Santana (Heather Morris and Naya Rivera) will be featured more prominently.

"They have some stories [coming]," said Falchuk. "Heather and Naya get to sing in the back nine. Heather is so brilliantly funny and brings something so special that it's entertaining us to put her in there and start giving her stuff."
