Nadine's explanation doesn't make it any less cool or dampen any of the wonder in Hilda's expression. It feels like an odd way to find out about the woman's ability but who knows if she would have found out otherwise. For a moment, it's like this is a completely normal conversation that isn't being brought up because the people they care about are missing.

Amusement flickers in her expression at both explanations as she teasingly says, "Lassie does sound pretty amazing, but can she also claim to be almost a doctor? You might have her beat there, Nadine."
