Oh God. Elsa hadn't thought this far ahead. She rests her hands on her stomach, and then inhales sharply when one of the babies kicks. Holding out a hand, she brings Anna closer so she can feel it. Anna smiles, and Elsa doesn't let go; she keeps her eyes on her stomach, unable to meet Anna's.
"I saw you today..." she starts. Anna's hand twitches, but remains where it is. Guess she's really doing this. "She looked nice."
"Elsa..."
Elsa shakes her head, forestalling Anna. "Does she make you happy?"
How can Anna answer that?
