Your character cannot be blood bound by anyone who shares his mortal bloodline. That is, if you were born into the Giovanni family, you cannot be bound by anyone else who was born a Giovanni, though you can still be bound by, say, a Pisanob of the Giovanni Clan, or by Kindred of any other Clan. Similarly, a Dunsirn with Consanguineous Resistance could not be bound by others who were born into the mortal Dunsirn family, but could be bound by a Milliner of the Giovanni Clan.

The Giovanni are extremely suspicious of anyone known to manifest this quirk. Although this blood-borne aberration hasn’t been documented, a few savvy Giovanni have a rough idea of what it is and does. It’s generally associated with being a rebellious young smartass who needs to be put down. This is not as unfair as it sounds; by the time a bond resistance is really obvious, it’s likely because a punishment isn’t working. A character who is discovered to have this trait probably earns her sire’s hostility at the very least.
