Zatanna uses a much more luxurious shampoo than Artemis.

It smells like lotus blossoms and vanilla, and Artemis could get drunk on the scent.

She takes every opportunity to. When they're sitting close to watch a movie, when they're sparring, when they're kissing.

Zatanna laughs when she notices. Artemis doesn't dignify that with a response. Her own soap smells of pine, the cheapest type her mom can find.

Then Zatanna changes shampoo, because she grew tired of it or something. Her new shampoo smells of strawberries or pure sugar, too sweet and too artificial.

Artemis loves it all the same.
