*It's Roddy they've hit, as he was just behind Bella. As he falls, he only has time to think: well, at least it wasn't Bella they hit. But the curse is nonlethal, and the thing seems to only be a simple blast of unfocused force, and the fall seems to have hurt hm just as much as the curse has. He's woozy, off his feet, but his unregistered wand is unbroken, and even on the floor he can cast a preemptive shield charm on his wife.*
