It isn't hard to hear the struggle. Metaari is just passing through the area on his way to literally anywhere but the Hinterlands when he hears the voice through the silence of the snow. He turns toward it, hesitating for only a moment, before he finally picks his way through the brush to the source of the sound.

He stops to rest his bow and quiver against a nearby tree before he moves toward the pinned girl, trying to gauge where he could best get a grip. "You alright?" he finally asks as he steps forward, bracing himself as he gets his hands under the tree. "If you've got any sort of grip and can push, we'll get this off you in no time." He could probably lift it enough to get her out from under it, but a little extra assistance never hurt anyone.
