She glances up when that slender arm grabs Danny's trousers.

"Go find them... I will help her onto one of these..." Hermione carefully moves the woman onto the stretcher. And calls out to two others who are helping search the rubble. "Quickly, each of you grab an end, and carry her to the hospital area."

How many people are trapped? Hermione listens for other voices. Others who need help.
