Isaac doesn't take a personal interest in many things...He prefers to follow Dracula's orders, sticking to his goal of wiping out humanity...You're one of Dracula's most trusted advisors, a strong, and skilled vampire, that he would be foolish to not admire...

He listens to you and always shows you an incredible amount of respect...He doesn't question your judgment and tries to keep you in his forge for as long as he can whenever you visit to update him...A mild infatuation, nothing more...
