For anon on tumblr, who asked for young Anna and Elsa and got...not that.
They try to smooth over things after everything melts, but explaining to the (mostly indifferent) subjects that their new queen has magical powers and had run away and now come back and that Arendelle was opening its borders after almost fifteen years of isolation is difficult work. Anna looks tired and the boy with her (Kristoff, Elsa remembers vaguely) looks tired, and Elsa feels tiredness clinging to her bones, so after a while she motions for Kai to take over and they make their exit.
Anna starts talking immediately after they leave the great hall, and doesn't stop; Kristoff rolls his eyes and keeps trying to interject, but Anna talks right over him without stopping. Elsa just smiles and leads them along—after years of silence, she doesn't mind the chatter. She doesn't mind at all.
There is something, though, that she should check—"Anna," Elsa says, and Anna falls silent instantly. Kristoff snorts. "Are you cold?"
Anna shakes her head. "No, it's—it's summer."
Elsa stops, and Anna stops. They look at each other, and Elsa feels her grin growing with Anna's. "It is," she agrees.
Kristoff stares at the two of them, and then throws his hands up, mumbling about how weirdness is definitely genetic and how he needs to find Sven. Elsa raises an eyebrow at his retreating back, and then looks back at Anna: how long have you known this one?
Anna shrugs, and Elsa knows it means long enough.
They're going to need to have a talk, she knows, and soon—about Kristoff, about Hans, about them and the years that had cut them in two. But now Elsa just enjoys the silent communication between them, and marvels at how easily some things return.
Anna starts talking immediately after they start walking again, but breaks off with a gasp when they reach their destination—a small rise on the side of the castle. "It's beautiful," she says, gazing at the sea below.
Elsa opens her mouth to reply, but Kristoff reappears at the moment, a reindeer in tow, and stands at the edge with them. "Has she finally stopped babbling?" He stage whispers, after a while.
An indignant squeal from Anna as she launches herself at Kristoff, and he laughs. Elsa lets them scuffle for a while, and then points at the sky, where a full moon was rising; they both stop to look.
"The sky's awake," Elsa says, and concentrates.
Anna stares at the snowflake dancing on the palm of Elsa's outstretched hand, and then at Elsa; her laughter is a mixture of wonder and delight that stretches back and back, to when they were both children.
Elsa hums a familiar tune, and then sends a shower of snow right in Anna's face.
