Gale was following as soon as he'd finished healing the first child, only pausing long enough to push bandages in an adult's hands for the more minor cuts that he did not heal. He nodded at the explanation as they moved.

"I will do what I can until my chakra gets too low, and hope more aid arrives. I cannot heal them all myself."

In spite of saying that, he was already kneeling in front of the worst injuries in the new group and giving the wounds a thorough look. It's bad.

"This might be better with seal use. Can you and your comrades use seals adequately?" It might be a little overkill, but Gale is better at seals, and it might conserve his chakra a bit if he can funnel the healing through seal structure instead of a more direct application of chakra. Others would be able to apply their chakra as well, if they're familiar with seals and can follow direction.
