Best Friends Whenever S1 E7

## Plot

Cyd, Shelby, and the rest of the class all get Fs on their essays. Their teacher wants them to write an essay about the 70s, specifically, disco. The teacher is an old guy who's stuck in his ways, he still likes disco and hates punk music. Naldo's dad was in a band in the 70s, and they played disco songs. Actually, they played punk songs, hated disco, and their band was called The Stench. The girls decide to go back in time to the 70s to do research for their essay and hear Naldo's dad's band play. Barry is against it, because it's uncharted territory. Up until now, the girls have only traveled within their lifetimes. There's no telling what could happen if they went back to a time where they weren't born yet. They go back anyways. They normally only perform mental time travel, i.e. entering their bodies from that time. It's revealed that they leave behind tachyon particles when they perform physical time travel. The particles are shaped like them. They mention said particles on *The Flash* too. The girls go back to the 70s, but when they take a time selfie, they look the same because of the aforementioned physical time travel. They get 70s clothes from the lost and found. Shelby talks to the disco kids to work on their essay, and Cyd meets Naldo's dad, who looks just like him. In the present, the boys notice them in the yearbook, but they didn't exist back then. They might be becoming a part of the 1970s. They could get stuck there and not be able to get back. Their teacher from the 70s gives Cyd and the rest of the punks detention, and Shelby is too busy spending time with the disco kids to notice that she wants to jump back. Back in the present, the boys notice another picture of the girls in the yearbook. They're not together anymore. Their tachyon signatures are drifting apart. If they forget each other, they won't be able to jump back to the present. Shelby forgets Cyd's name, and meets Barry's dad. In detention, Cyd forgets Shelby's name. Shelby gets purposefully thrown in detention to find Cyd, but neither recognizes the other. Their tachyon signatures are disappearing. The boys try to come up with a plan to save them. They plan to use the laser to blast the particles and open a wormhole to the 70s so they can go through and rescue the girls, but the particles disappear too quickly. Naldo is able to capture some in a jar, but they've lost their only connection to the girls. They're lost in time, and the guys may never see them again. The punk kids start picking on Shelby, but Cyd stands up for her, and vice versa. They remember each other, their friendship ends the feud between the punk and disco kids, and they return to the present. The moment they get back, the boys drop whatever they're doing to run over and hug them, relieved that they're okay. Barry plans to study the tachyon particles to understand time travel. The girls jump back to the 70s for a song, performed by Forever in Your Mind. One of their members was Ricky Garcia, who played Naldo. They also performed the theme song, and one of the other members played Cameron in the first episode. During the credits, the girls accidentally jump back to the future lab again. This time they notice a logo. They don't know what it means, but now they have a clue. The same logo is on Barry's laptop. And he's determined to figure out the answer to time travel… Spoiler alert: He has something to do with the future lab, and yet he doesn't. Confused yet? I know I am!

## Review

This was a great episode. Some ground rules and limits are established on Cyd and Shelby's time travel power. They shouldn't travel outside their lifetimes, and if they do, they can't stay too long and they have to stay together. I wonder what would happen if they traveled to a time before one of them was born but the other one was? One would look like her present self due to physical time travel, but the other one would be in the body of a baby due to mental time travel. Naldo and Barry worrying about the girls is so sweet. I love their reaction when they finally get back: Group hug!
