Stupid girl, if she hadn't grabbed Porta, he wouldn't have been hit. It looks like it hit around his neck or upper chest, which means she lifted him into the blow. Even without that, if she had intercepted the monster instead of grabbing him, that would have been far better.
Reminds me of many experiences with my parents growing up. Thank God I have outstanding reflexes and quick thinking in danger. I would absolutely be dead several times over or missing limbs otherwise solely due to my parents trying to "protect" me by doing that sort of stupid shit.
