Being dead wasn't enough to cover the bear's current state in front of Revna. At a glance, one could tell that the beast had taken a lot of punishment, although the internal damage actually killed the beast.
An average person should be extremely excited and proud of themselves for being able to defeat such a creature, but Revna is not a normal person. Desmond brought her out of hell, so she was unsatisfied with the result. She didn't think Desmond was satisfied either.
"I'm sorry, Master."
Revna's apology was as sincere as possible; however, that did not take away the strangeness of the girl's attitude. The prowess displayed by Revna was no less than Desmond's in the not-too-distant past. This was no longer a matter of vanity; Desmond knew very well what kind of monster he was. He didn't expect to have someone as talented as Revna under his wing.
