Author's Note:
Patronustrip's series of posts on Dark!Elsa giving Dark!Anna her own ice weapons, in particular her own dagger at 14, inspired this. A little language here and there never hurt anyone, but Anna might.
Knives Are Not Toys, Anna!
In retrospect, she probably should've chosen her words more carefully.
Elsa's gaze took in the room slowly. She looked over the piles of books pulled hastily from the shelves, some slashed into many pieces, others bearing conspicuous wounds. She looked at the chairs, at the matching cushions several yards away, the fabric torn and insides spilling out. She looked at the old grandfather clock, ironically an actual gift from their grandfather, with its broken glass and hands twisted into a crude smiling face, the sides peppered with holes.
