This time there was regret.
A loud bang sounded, his head thrown back from the sudden impact from the direct hit to his horn. Kat's aim was true and precise and had unfortunately hit the horn he had previously damaged. Under normal circumstances his horns would have taken the damage without much to show for it but she had hit the crack he had just recently mended and with an easy snap his horn went flying while he was left to land flat on his a**.
The demon sat there a moment dazed and confused, shaking his head and wondering why one side felt heavier than the other. It was when his hands came up to check for injury that he realized what was missing.
"W..what? What the-?" He continued to feel around the damaged horn in a frantic manner as if he couldn't believe what had happened. He stood to his feet a second later and when reality set in he let out his panic in a gut wrenching yell.

"WHAT HAVE YOU DONE?! FILS DE PUTE! JACK DAMNIT!" He continued to yell and scream at the top of his lungs switching between English and French at random because neither completely did justice to his shock.
