Lav finding Ulla after their first row.

Ulla (despite being a hundred and six) is not reasonable, reflected, or at all mentally stable. Her reaction was thus to snap and go on a murderous rampage of epic proportions. Hulderfolk only kill humans to feed, so her behavior would be the equivalent of you going out and slaughtering every animal in sight for two days straight merely because you could. Hulderfolk and their ilk usually prefer a clean drowning; Ulla’s literal bloodthrist is highly uncharacteristic.

Lav mostly feels like slapping some sense into her, this whole affair being far too melodramatic for her tastes.
