This has to be the most fun thing about my most developed character, Dandre. Throughout his life he always wanted to be helpful to others. Even when doing tasks like chopping wood for a miller all day, he was willing to do it. After traveling to Skyrim and getting infected with lycanthropy his mind began to change into something twisted. He began not caring about others, seeing them only as prey. He joined the DB and his only friend was Abjorn, he also enjoyed Festus' company too. He soon found a man he didn't see as a meal, Marcurio. The old side of Dandre flourished around Marc, he wanted to please him, often showering him with gifts. He would obey what Marc said (Role Playing, Marc hardly says anything.) if he suggested that some bandits be dealt with before they go any further Dandre was the first one in the door. That servant nature in Dandre came out when he was with Marc, although he would only serve Marc and no one else. In werewolf or wolf terms, Marcurio was the alpha male.
Dandre lived a double life, not wanting Marc to know his dark secret (Being a werewolf and a DB member.) The guilt of leading a double life only surfacing when he was with Marc. He'd sometimes leave him to go serve a Daedric Prince so he could receive a reward, or go to the ancient DB assassins tomb or something. That ended when he repented for his actions. He tried to follow the way of the voice, living at the Greybeard's monastery and searching for words and meditating. He got frustrated and fell back on his old ways a bit. I can't say he reached enlightenment and became a saint, just like Paarthurnax there is not a day where he is not tempted to return to his evil ways. He may have destroyed the DB and renounced almost every Daedric artifact, but that doesn't mean he still doesn't have the craving for power and a hunger for the hunt.
It takes a lot to gain his trust, and even more to be accepted by him. He will look down on almost anyone except Marc. He never has mercy on his enemies, but he looks after his pack (Marc, Inigo, Paarthurnax and Odahviing.)
