Elsa's stomach is more pronounced, and Anna just wants to put a hand on it and marvel. She doesn't. She just sort of stares, because Elsa is the last person she expected to see. She looks so... soft. If that's possible.
Her eyes light up as soon as they land on Anna, and she takes a few steps forward. Anna's still a statue, silent in shock. It isn't until Elsa speaks up, a soft, "Hi..." that she jerks up.
"H-hi me?"
Elsa nods and smiles, and Anna feels her own light up her face.
