Sabrina Carpenter

Super important.

And she seems pretty confident with her performance.

Back at home, Erica is watching Courtney leave for the race with Randy and her dad.

She's obviously bummed, but wishes them luck.

Now with a rare free weekend, she has no idea what to do with herself.

She's just bored and sad and laying around the house.

At the racetrack, Courtney continues her winning streak, forcing Randy and Greg to perform a celebration that includes the running man and a chest bump.

And once the weekend's over, they return home to Erica asking Courtney how she did.

But instead of an answer, her little sister gives her some real sass.

And that night while getting ready for bed, the girls finally talk it out.

Courtney is mad that Erica quit because now racing isn't fun without her.

Erica explains she quit because of reasons that are hard to explain, which isn't explaining anything.

But Courtney thinks it's because she's scared she'll lose to someone, maybe even her.

And now back at school, Erica got her French final back because now this film is just about French.

And she got an A. Hey, she did it.

She jumps up and squeals, yes, we, in class, startling everyone in the process.

And just like that, she's unpacking her trophies and returning to racing.

She's back on the track like she didn't miss a day.

So she qualifies for the Nationals with an impressive 8.87 seconds.

She quit for a weekend.
