Whether Ehren fully understood him or not, Aldaric believed they were more alike than Ehren realized. Truly, Aldaric envied what the pureblood had had so long ago, the position of a god, dominance, to have been worshiped and feared, even if he had offered some form of protection to his cattle in return. There was no shame in caring for humans, even loving them, as long as proper respect was maintained. Humans had to be kept under control, not vice versa. Such as Aldaric Weirven's opinion. 

Aldaric kept quiet for a moment as he listened, noting the direction of those red orbs. As Ehren turned with his last words to depart, Katarina would be suddenly caught off guard to find Aldaric was peering down at her silently from the corner of his eye while she casually held his arm. He sensed her consternation, but did not give voice to it. Exhaling a soft sigh through pursed lips, Aldaric took his gaze off her and watched Ehren exit out of earshot, apparently thinking. 

Finally he reached a decision. "Katarina." He let go of her arm intentionally. "I want you to follow him. Learn what you can and report back to me." He told her this coldly, revealing nothing of his true thoughts. It was a simple spy mission. In truth however, Aldaric knew the pureblood had suffered, and was being hunted by the Society just like the rest of them. Even if Ehren didn't fully appreciate Aldaric's slightly warped logic, he was an ally. 

Ehren would also be a far better influence on Katarina than he himself would be in his tenuous sanity, and Aldaric knew it. Plus, the two of them together would better able to protect each other against an executioner, should they be attacked. The pureblood might have been too proud to admit it, but even he, with his feral power could be destroyed if the advantage were against him. Aldaric wasn't about to let anymore innocent vampires be slaughtered by that cowardly, human-worshipping cult. It was just insulting.
