Fallen eyes

I shouted a panicked battle cry and gave her the pepper spray full in the face, right into both sets of eyes.
The demoness screamed again, twisting her face away, ruining the tendril-cage, the human eyes squeezing shut over a sudden flood of tears. The glowing demon-eyes did not even blink, and a sweep of the Denarian's arm fetched me a backhanded blow that sent me sprawling and made me see stars.
I got back to my feet, terrified at the notion of being caught helpless on the ground. The Denarian seemed able to blow off my magic with a bit of effort, and she was deadly in these confined quarters. I didn't think I could get up the stairs without her tearing me apart. Which meant I had to find another way to get the demon away.

Ursiel was too big to fight.
Look, people go on and on about how size isn’t everything, and how the bigger they are, the harder they fall, but the people who say that probably haven’t ever faced down a charging demon-bear so big it should have been on a drive-in movie screen. As a defensive adaptation, sheer size is a winner. It’s a fact. Ask an elephant.

If the Genoskwa had been able to pursue me in his natural form, he would have caught me and torn me apart in short order—I’d seen him move. The bear might have been an irresistible mass of muscle, claws, and fangs, but I’d had a little experience with very, very large creatures on the move, and I’d learned one important fact about them.
They didn’t corner well.
Ursiel closed in and went into a little bounce, a motion as close to a pounce as something that size could manage, and I darted to one side. Harry Dresden, wizard, might have bought the farm right there. But Sir Harry, the Winter Knight, dodged the smashing paws and snapping jaws by a tiny margin, hopped back several yards, and shouted, “Olé! Toro!”
