You get called up to sniff the amortentia potion. You walk up and sniff it

Snape: well, what do you smell?

"I smell... cologne, mint, and.. toffee?" You say

Blaise grins widely since that's how HE smells like

he goes and sniffs it

"I smell... vanilla bean, candles, and dior perfume" He says

your eyes widen as he describes YOUR scent
