The old gang’s all here to celebrate Thanksgiving and help the newbies prepare for sectionals.

But coming home isn’t always easy as Mercedes, Quinn, Finn, Puck, Santana and Mike express in their return medley.

The previous members of New Directions slow things down with their mash-up of Simon and Garfunkel’s “Homeward Bound” along with “Home” by Phillip Phillips. With little else but a piano, the gang goes for a quieter take, letting the lyrics speak for themselves.

With past grads home they decide to come by the old high school and help Finn out with the glee club. The Unholy Trinity-Quinn, Santana and Brittany—even reunite to teach the ladies a thing or two about singing with their tride and true rendition of “Come See About Me” by The Supremes.

Off in New York City, Kurt and Rachel are having a quiet Turkey Day celebrating like orphans. But the duo gets a special guest when they’re joined by fellow misfit, Isabelle (Sarah Jessica Parker).

The trio go disco with their combination number that mixes Scissor Sister’s “Let’s Have a Kiki” with “Turkey Lurkey Time” from the musical, Promises Promises.

We imagine this is probably not your grandmother’s kind of Thanksgiving.

While some would take a few days to recoup from feating, these kids have to get back to work. It’s sectionals time people! And the stakes are high this time around. So high in fact that at least one person gets slapped in the face.

The boys of the Warblers are back and they’re going pop with an impressive cover of One Direction’s “Live While We’re Young.”

They also tackle hip-hop with their cover of Flo Rida’s “Whistle,” which shows off their impressive whistling skills.

New Directions on the other hand tackles Psy and his viral hit “Gangnam Style.” Yes, it finally happened and it only took eight episodes!

Tina even gets a chance to show off her Korean, which actress Jenna Ushkowitz says she learned in a week specifically for the episode.

What do you think? Do they have the chops to win sectionals?
