10 details you may have missed on the latest episode of 'The Last of Us'

That's a nod to a Walkman that Ellie carries in the game.

While Joel is incapacitated, players take control of Ellie to find medicine for him. You're able to see what she's carrying on her. Among other artifacts is an old Sony Walkman that Ellie says she should fix.

When Ellie gets into trouble, she looks at a photo with two girls at an amusement park on Captain Kwong's desk.

Those familiar with New Jersey may have recognized the theme park as Six Flags Great Adventure. Kingda Ka and El Toro are two of the coasters that can be seen in the background.

When Kwong tosses his keys down onto the desk in front of Ellie, there's a red paw print on a keychain. The paw print's featured on the logo for Naughty Dog, the video-game developer of "The Last of Us."

Neil Druckmann, one of the show's creators and showrunners, is also the copresident of Naughty Dog.

Players often passed by posters for the fictional movie in the game. Joel told Ellie that he had watched a "dumb teen movie" before the apocalypse, presumably with his daughter, Sarah. You can actually spy a poster for the first film in Sarah's room at the start of the game.

Some fans thought the poster hinted at the events of the sequel game and, without spoiling much, Joel's role toward Ellie.

We hear Rockabye Baby's lullaby rendition of The Cure song on the show's seventh episode as the pair ride the carousel. In the game, the carousel stops before Riley's able to ride with Ellie.

The original song was inspired by a trip The Cure's frontman, Robert Smith, took with his then-girlfriend before they married, and the song talks about the thought of running away with someone you're in love with. By the episode's end, after a whirlwind night at the mall, that's what Ellie and Riley plan to do until Riley's bit by an infected.

You can spot the poster near the start of the episode. Ellie previously expressed her love for this game on the show's third episode when she found the Mortal Kombat II arcade game on episode three.

""I had a friend who knew everything about this game," Ellie told Joel. "There's this one character named Mileena who takes off her mask and she has monster teeth and then she swallows you whole and barfs out your bones."

We finally see that happen on episode seven.

In the game, Ellie and Riley come across a fictional game called "The Turning."

On HBO's official "TLOU" podcast, cocreator Neil Druckmann said they used "Mortal Kombat" because it was the original inspiration for that moment in the game. They couldn't use it in the game because of licensing rights. HBO and "Mortal Kombat" are both Warner Bros. properties so it was easy for Druckmann to use the game on "TLOU" show adaptation.

That's a nod to a doll store, American Princess, Ellie enters in the game's DLC while trying to find medication for Joel. Ellie discovers a similar infected inside of the store whom she acquires a pharmacy key from, but he's long dead.

During an interview with Insider's Palmer Haasch, "TLOU" production designer John Paino estimated they created about 40 stores to a completely stripped mall in Canada.

"In the game they could not use real names of anything. So we were able to do Victoria's Secrets, Starbucks," Paino said of why the doll store on the show was an actual American Girl shop.

An Etta James cassette was quickly shown in Ellie's room at the top of the episode.

The duo invade a Halloween store called Spooky Town in the game. Riley scares Ellie in the clown mask seen in episode seven and encourages Ellie to put on the wolf mask and give her best roar.

Players are then able to walk around the store and have Ellie try on a few different masks.

On the show, the two girls only face off against one infected. In the game, tensions are a lot higher. They're chased through the mall by a herd of infected and get bitten while making their escape.
