There's actually another appointment after the ultrasound. Like, a real appointment, with a doctor and everything. It's the first time Anna's been here for that, but Elsa tells her it's not the first appointment. Maybe one of those things, when they shared ''her'' apartment. Elsa had her little adventures.
The doc is happy Elsa's reduced her dose, but he still gives her a month supply of pregnancy vitamins. Iron and folate and yeah Elsa does look quite pale...
And then he takes Anna by surprise when he asks, "Have you looked into birthing classes yet?"
