Hermione was leaned up against the counter of Molly Weasley's kitchen in the Burrow, watching through the window as assorted Weasleys and friends played an unusually violent game of Quidditch in the yard. Her fork was poised above a slice of Molly's decadent chocolate cake, when she sensed a presence behind her. Swiftly, she moved her fork to block the incoming attack.
"Mine, Fred."
"How do you always do that?"
"I take your mother's cake very seriously."
She felt more than heard the sigh behind her. "You know that's not what I meant."
"Tell you apart from George?" Hermione gave her best Gallic shrug, perfected by observing Fleur in action. "How do you tell Ron and George apart?"
"George is missing an ear." Fred replied smartly. Hermione deigned to give him an arch glance and returned applying herself to her cake. "But you don't need a missing ear to tell. Even Mum has trouble sometimes, but you never have."
"I don't know if you've noticed, Fred, but you are actually entirely different people." The swat on the bum he gave her in response was well deserved. "You can't expect a girl to give up all her secrets, can you?"
"One or two might be nice though." Hermione quashed the swarm of butterflies she felt suddenly in her stomach as she felt him step in nearer to her.
Hermione turned and tapped the distinct cluster of freckles on the right side of Fred's jaw. "George's is on the right." She missed seeing his jaw tense as she turned back to the game and her cake and added "You're not identical, you're a mirror."
This time she allowed him to steal his bite of cake.
