On one hand, Isaac has a flash of worry because a regular wolf would act very differently. On the other, he hasn't seen or smelled any large predators of any sort in the area, except maybe the ravens.

He can't really check out her ankle more thoroughly like this, not without hands and the ability to ask questions, but he doesn't think it's badly injured. Twisted or lightly sprained, maybe, but it's impossible to really tell. Still he can't leave her out here, but he can't really walk back with her either. The dilemma has him staring off at nothing for a moment but then Isaac gets an idea. If the ankle hurts, she might be able to walk faster with some support. It wouldn't hurt, at any rate.

He dashes off and comes back with a large downed branch in his teeth. It's not all that straight, but it's not rotted and it's long enough to be used as a staff to lean on. Isaac deposits it at her feet and does his best to make his muzzle look like a smile.
