Strangely enough, it wasn't Marius who brought Eponine to the Independents, and it wasn't Grantaire. It was Courfeyrac. When Gavroche asks to hear the story, Eponine turns bright red and covers his ears the second Courfeyrac opens his mouth, and the subject is dropped. However, a few months later, Musichetta has a little too much scotch and suggests they play Truth or Dare (apparently she was deprived of all the bitchy slumber party mayhem when she was in high school), and the first thing Gavroche does is ask again.
"Well…" Courfeyrac pauses, unsure of how to begin.
"Courf, shut up." Eponine's face is slowly turning the color of the hoodie she's wearing, a very unflattering shade of vermillion.
"'Ponine, darling, I'm not going to lose the game just because you're a little squeamish," he says patiently. "Now, let's see. So, I was at this sleazy bar over on Sullivan Street called Corinthe—"
"That's where 'Ponine works!"
"Yes it is, my son. I was chatting up this foxy guy with glasses…"
"Courf, you were trying to chat me up. Unsuccessfully, I might add," Combeferre interrupts, not amused.
"As I was saying. I was successfully chatting up Combeferre, and I noticed this fine-ass waitress—spoiler alert, guys, by the way, that's Eponine—and I just had to go say hello."
"When he says, 'say hello,' what he means is, 'puke all over me.'" Eponine wrinkles her nose at the memory as Musichetta gags and Gavroche laughs.
"No!"
"Yes," the two say simultaneously, Courfeyrac proud and Eponine deadpan.
"No wonder you didn't wanna tell this story, 'Ponine!" Gavroche laughs again, totally amused by the idea of Courfeyrac throwing up all over his sister.
"The best part is—"
"Shut up, Courf."
"I'm not done telling my story!"
"Courf. Shut it."
"The best part is, she still slept with me after!" Gavroche stops laughing, looking like he can't decide whether to be more grossed out with Eponine or Courfeyrac.
"Courfeyrac. I cannot believe that you just told my little brother that I slept with you."
"I can't believe you slept with Courfeyrac," Grantaire sniggers.
"Shut it, you."
Later, when it's Gavroche's turn again, he dares Eponine to kiss Courfeyrac, clearly over his earlier revulsion, impish grin spread across his face. "You are evil," hisses Eponine as she attempt to walk on her knees over to where Courfeyrac is sitting.
When she kisses Courfeyrac, however, neither of them pulls away until the catcalls and wolf whistles have subsided, and Gavroche looks significantly less pleased with himself; the sight of his sister's mouth melding with Courfeyrac's is a sight he could have lived without seeing.
"Yep," Courfeyrac says after they finally separate. "I still got it." Eponine smacks him, but when he grabs her hand playfully, she doesn't let go.
