【The Relic Of My Sister Next Door】

As a TV adaptation of Naughty Dog's games,The Relic Of My Sister Next Door The Last of Usincludes more than a few hidden references and overt re-creations of the gameplay and cutscenes from The Last of Us Parts I andII.

Music references, in particular, are threaded through both seasons, from the Hank Williams connection to Season 1, episode 4; Crooked Still playing at the dance in Season 2, episode 1; to Ashley Johnson's cover of "Through the Valley" to end that brutal second episode.

In the fourth episode of Season 2, Ellie (Bella Ramsey) plays a tune right out of the game, in what's sure to be a moving moment for fans familiar with the TV show's source material. But what song does she play, and how is it connected to the game?

Which song does Ellie play in The Last of Us?

In Season 2, episode 4, Ellie and Dina (Isabela Merced) are en route to Seattle when they need shelter. They find the one place they can fit their horse Shimmer through the door, Valiant Music Shop, an abandoned record store that's still fully stocked with Bob Marley and Tears for Fears vinyl and requisite Pearl Jam posters.

Ellie heads upstairs and finds the guitar section, where many an instrument has been eroded by the elements. But fortune smiles on an unopened case, and Ellie finds a pristine acoustic guitar within. She picks it up, takes a seat, and plays a truly beautiful, quietly romantic version of A-ha's 1985 track "Take On Me."

Why does Ellie play "Take On Me"?

Music is a crucial link between Ellie and Joel (Pedro Pascal) in The Last of Us, in life and after his death. Joel gave Ellie the butterfly-necked guitar and was restringing it for her before he died, despite their rocky relationship.

The song Ellie picks to play is the same one as in The Last of Us Part II,when you play the chords yourself (this feature of the second game is a polarising one). Ramsey performs the song in the show in much the same style as Johnson does in the game, with both scenes showing Dina listening with shining eyes to Ellie's rendition.

In the game scene, Ellie actually starts to play Pearl Jam's "Future Days", a song Joel plays to Ellie at the beginning of The Last of Us Part IIwhen he gives her a guitar, and a song that's become synonymous with the franchise for fans. But then Ellie stops when Dina enters, then moving into A-ha's "Take On Me."

The thing is, you could completely miss this cutscene in the game if you don't investigate the guitar room. It's not part of the main storyline, but instead it's more of a private side moment for Ellie, who is still grieving the loss of her guitar-teaching father Joel, and for Dina, who is becoming more aware of her feelings for Ellie — you try watching someone you mightlike playing music live and not falling head over heels.

• 'The Last of Us': The song at the end of episode 2 has deeper meaning
• 'The Last of Us': Ellie hides a dark secret from Dina, and who could blame her?

But it's particularly poignant because of A-ha's lyrics, which match The Last of Us' glimmer of hope for our protagonist, with Ellie singing, "Needless to say / I'm odds and ends / But I'll be stumblin' away / Slowly learnin' that life is OK."

The Last of Us Season 2 is now streaming on Max. New episodes air weekly on Sundays 9 p.m. ET on HBO.
