We don't have any battle animations for Marie, and two NPCs battling would be chaos anyway, so I'm thinking this:
If you hit Marie, she dies in 1 hit because she's brittle and old. Dyna starts to attack (we have fight animations for her) with generic NPC combat script.
Instead, if you hit Dyna first, she starts fighting you, while Marie plays her "afraid" animation.

I will try implementing this today!
