She'd saved him.

[i]Why?[/i]

Heart thudding in his chest, the wavy-haired Thief could barely comprehend what had happened for a moment. They'd been running, he'd been wheezing from the effort, pace slowing, body failing him-- and then--

[i]Is she all right?[/i]

Stunned on the ground where he'd been pushed at the last second, tall grasses arching over his head, Matteo didn't know.

A storm of hooves and then Ash being tossed towards him was enough to shift his thoughts to other things. Awed by the dual close calls he’d had with first the toad attack and now a flying ranger, Matteo gave a jerk as Ash shouted at him. Secretly relieved that his task of protecting the priest had been taken from him (it hadn’t been his idea to begin with, so of course it wasn’t going to be any good) he looked around for Muu. 

[b]“Ah! Right,”[/b] he said belatedly to Ash, recovering, and then took off at a stumble and then a full run. Even after their brief rest, his muscles screamed at the effort. He could see Muu’s bright red scarf over the tall grasses and hurried towards it. The bladedancer was walking, at least-- [i]that’s a good sign.[/i] [b]“Muu! I’m right behind you, keep going!”[/b] he shouted as he drew near. 

From here with his nearsightedness (and lack of glasses) the girl still seemed all right. Certainly injured somehow, but not (obviously) disfigured. Still calling out, urging his fellow amnesiac on towards a more toad-free zone, Matteo had to trust the other three would be all right.
