Two days before the appointment, Elsa wakes up with a desperate need to puke. It's her first encounter with morning sickness; she manages to call in sick before spending the day hugging the toilet.
Anna's already at school, and Elsa can't even help it when she begins to cry because all she can imagine (years of dreaming, if she's honest) is warm hands on her back, soothing her.
Not being alone.
When Anna comes home, though, she brings ginger-infused tea and sits with Elsa; distracts her with antics of her day.
It's... really nice.
