Danggggggggggggggggggggggggggggggggggg.
Arwin plays NO GAMES. Like, we know theres a reason he is the most feared person... He didn't get that reputation for nothing. But honestly, I'm satisfied that he went there and handled her. Cuz why not? She gonna learn today!!!
Also, the fact that he went straight to killing her leaves me with mixed emotions. It might be that he set his magic to "kill" her only as many times as she killed others of her own will, which would mean that if she were innocent then she would be fine.
