xD He knew she'd be fine because of the Vampire in her, but of course she could tell his thought process from a glance rofl.
If he realy though that then why even think "What should I do? I can't save both of them at the same time!" and "If so, which one should I save? The short-tempered blondie? Or...". The naritive of him knowing she could save herself doesn't pass if he contemplated having to choose between who to save.
Lols because he didn't realize it, when faced with that situation logic is out the window. He knew she'd be fine, but at that moment he forgot and saw her as an endangered life he needed to save along with the other, since in his mind both were important to his life in different ways.

All this time he's been doing things by the rules of wolves/nature. So why now when the woman he made train and get strong to only then aknowledge her as his mate, when she's in danger he has to stop and think which is more beneficial to save between HIS MATE or another woman. Also aren't wolves monogamous, they better not be heading to a harem route. They really wanna pick and choose which wolf traits he's gonna follow.
