She's prepared with oils and the situation is so desperate that she throws bruise oil to her husband before saving her own child from the horror of a minor fall. Mickey Mouse and the police stood there clapping and demanding their own DoTerra business where they can be their own boss.

In the books they don't even use oils (and barely ever use potions or signs, for that matter) most of their gimmick is just being good at the witchcraft known as stabbing a mfer with a sword.
