i love it! damian comes from a storied family tree that stretches back as far as the middle ages in europe and branched to america during the colonial period. he's the middle of three boys and the only one to receive witch abilities while his brothers remained human, so he is somewhat sympathetic to humans and their plight, probably on a more secretive level. maybe their families were lifelong retainers of each other? their ancestors could have protected and looked out for each other as a way to ensure survival. now damian and quinn — probably childhood friends maybe? — protect each other as a way to keep 'the pact' alive?
