The thing about that trident to keep in mind? It's double-ended. Twice the stabbing for the same amount of grip.

His wheels let him dodge away far too fluidly, but Meenah only has to follow his movement a little with his head to see where he's going. And then she doesn't even need to turn around or readjust her trident to jab backwards at Casey with the opposite end, just as sharp and pointy as the other side.
