This one is for Sale. I interpreted Nessa like this because I knew Sale would like it.
Nessa rolled into her sister's dorm and giggled. "Hmm… blueberry…" she gushed.
Elphaba gave her a look. "Blueberry?"
"He uses…" her eyes widened, "blueberry shampoo."
"Who does?" Elphaba asked, and then realized how stupid the question sounded.
"Well, who do you think!?" Nessarose responded to her sister, rolling her eyes.
"Umm…" she said. "Biq?" She then smiled evilly.
"Hush… his name is Boq… but oh, it smells so good." Nessarose put something up to her nose and inhaled deeply.
"What's that?" Elphaba asked, suddenly suspicious of her sister.
"Um. Nothing." She put her hands down.
Elphaba cleared her throat.
"Okay, you've caught me… I've been, um… using."
"Using…?" she pressed. "Using what?"
Nessa's eyes flickered back and forth. "Tobacco…" she murmured. "Or… crack possibly… something you sniff…" She cleared her throat. "But, I can't remember the name…"
"Oh, really?" Elphaba came up and looked down at Nessa's perfect—but oddly cheesy—smile. In an instant, she had taken Nessa's 'crack' from her hands.
Nessa attempted to jump up to get it, but failed, sulking.
"Odd, this crack is fuzzy… and… hairy…"
"It's a new brand!" She flailed for it.
"You've snipped off a lock of Boq's hair!"
"My, word, I have not!"
"Yes you have!"
"Have not!"
"Yes you have!"
Nessa turned red. "I told you! No I haven't!"
"Nessa, it smells like blueberries!"
"I know… doesn't it smell nice?"
